Stuck at Initial Asset Database refresh (v2)

This bug still occurs with AssetDatabase v2 even with the latest a17 build. I am opening a very minimal project and it will hang forever.

https://issuetracker.unity3d.com/is...-meta-file-containing-big-amount-of-user-data

 

Here is an example with deleting the library. It's been stuck on this file for... well you can see.

 

They both still occur. In this case if I delete everything: .vs folder, project files, UserSetttings folder, Library, obj folder, and leave only the basics I can get it to open again. Then upon opening another time the "Initial Asset Database Refresh" occurs again. I will try to give send the repro project if I can get it to open again.

Note that just deleting the library leaves me in the previously 8hour long state.

EDIT: Case number 1263658

 

After I paste some asset into the Assets/ folder which doesn't have file extension, I encountered this problem. I simply deleted the wrong file, and it works again.

 

I'm experiencing huge delays now due to this same issue in Unity 2020.1.6f1, and it's causing me hours of lost time, having restart Unity constantly.

 

I don't personally leave the package manager window open, so the issue isn't that.

Unfortunately I can't provide a repro project because our project is massive.

The issue I'm seeing is happening any time a script recompile is required, and it's not just the AssetDatabase.Refresh that gets caught for 6+ minutes, it also gets caught on "Importing Assets" and a couple of others that I can't recall off the top of my head.

 

And just to expand on this a little further... it's getting to the point where I'm losing hours of time every day because of this (it's happening every second time I run our project now, so I'm restarting 50+ times a day), and I can't wind back to 2019.x or go forward to 2020.2. I'm stuck in limbo with this until a resolution comes along.

I'd be more than happy to get on a call with a developer at Unity and walk them through what's happening.

 

Are you by chance using Odin Inspector? If you are not, are you perhaps doing any Type scanning / attribute scanning inside of a static constructor or even through InitializeOnLoad/InitializeOnLoadMethod?

Odin Inspector has since found a workaround but the culprit in their case is that during those times Unity has not fully loaded assembly information and querying one assembly that may load another can cause a deadlock. From my recent experience Unity has a number of issues related to Assembly reload / settle including but not limited to the issue you're having as well as certain assets being displayed as "None" in the inspector.

 

Yes I am actually using Odin Inspector, and I try to avoid any initialise on load behaviours.

Would you happen to know off the top of your head where the information regarding Odin's workaround is located? Is it on their forum?

 

It's not. I don't think it was officially announced in any way as not everyone was having issues. I did help them work through the issue though and the fix required changing some initialization for types and attributes at the core of Odin. Ideally Unity would fix this issue but so far they claim to not be able to reproduce it even when I sent a project that 100% reproduced for me.

I cannot recall if it was back-ported to the 2.1.13 release. Your best bet is to hop on to the Discord and ask their staff if that fix is in 2.1.x or if it's only addressed in the new beta (which is what I'm using).

 

Thanks KAJed,

I was thinking about trying out the 3.0 beta anyway, so I might do that and see if the issue persists, and then contact them on Discord if I'm still seeing the issue.

 

I grabbed the 3.0.0.3 beta and I'm still seeing the issue, so I've sent them a message in Discord. It'd be such a relief to have this issue resolved - it's getting to the point where I'm wanting to just walk away from my PC all the time now when it happens.

 

Reinstalled windows and can't open project again. Unity 2020.3.13 Unity stuck at Load Scripting Assemblies.



Last log line is:
Application.AssetDatabase Initial Script Refresh Start
I don't know what to do.

 

Hello.

FYI, in my case it was resolved by changing permissions of the folders involved, giving full control to the user. Somehow the permissions were corrupted while installing a new operating system.

Also, removing some .meta files was needed in order to Unity to recognise some files.

 

Just now I had the problem of being stuck at "Initial Asset Database refresh".
My temporal workaround is to set the command line attribute -DisableDirectoryMonitor.
At least the editor opens up again now.
Not sure what this means for me.
It is not documented here https://docs.unity3d.com/Manual/EditorCommandLineArguments.html

 

That attribute is mentioned in this documentation page:
https://docs.unity3d.com/2021.1/Doc...setDatabase.IsDirectoryMonitoringEnabled.html

 

I see the same issue as everyone else. But interestingly enough, I only get stuck on Ubuntu. On Windows and Mac, it takes a long time to load, but on Ubuntu, I get stuck forever.
This issue happens even if I change the Unity editor version. Considering that other projects can load without any problem on Ubuntu, it might be due to a dependency I use (notably Odin Inspector and SuperTiled2Unity, which are probably the heaviest I have).

 

The -DisableDirectoryMonitor command line argument also worked for me. I was trying to open a Unity project containing symlinks in a virtual machine (Windows 10 host, Windows 10 guest, VirtualBox).

Thanks for the reference, the docs say that "Directory Monitoring is automatically disabled when Unity detects symlinks in the project," but maybe it has trouble detecting them within a VM. Good to know!


And remember: if you disable Directory Monitoring, you can use Ctrl+R/CMD+R to manually reload from disk.

 

Thank you for the advice. It worked for me. Are there any consequences, though?

 

i just solved this issue, i found out that i had some files and directory with root permission
chmod -R 777 directory/ ran this commend on the folder and the asset database will work again.

 

Worked for me! Thanks!

 

Currently having similar issue with the project (even the fresh one) on LTS 2022, no matter the version. Loading stucks on Initial Asset Database Refresh and spams editor log file with "Connectivity with IL Post Processor runner cannot be established yet. Retrying."
Any of abovementioned methods don't work at all. Any ideas how to fix this?

 

I had this same issue today (Initial Asset Database refresh) I was attempting to build my library on a brand new harddrive. The first attempt was after deleting the library (~50GB) and "moving" a perforce repository from c:\repository to the new drive d:\repository then opening the project.

When trying to open the project unity would hang forever doing the database refresh.

Then I deleted the entire repository and did a fresh sync from perforce, but Unity stalled opening the project again.

After reading this forum thread I tried -DisableDirectoryMonitor but I didn't fix the problem. But I started to suspect the file system was the problem. I chose exfat for my new drive.

I reformatted the drive to NTFS and downloaded the project from perforce and unity now seems to be rebuilding the library correctly. (It takes an hour or so.)

It may have been the exfat filesystem, but it may have just been some other issue with a file in the repository that changed.

I was surprised to learn that Drobpox will flat out refuse to save your files on exfat and it only supports NTFS. Perhaps perforce or Unity also have problems with exfat.

 

The issue in my case was totally weird.
I have an .net 5 API project running. That I use to store data for my game.
When I checked the Editor.log file when I was experiencing the "Initial asset database refresh" issue, I found the following:


[Licensing::Client] Successfully resolved entitlements

If you ask me how the f*** I get this exception when trying to start the game ... I have no idea, But the thing is that when I stop my API project. I am able to start the Unity game.

I will try to investigate further, but so far, I have no idea what exactly is causing this problem.
I tried changing the port of the API from 5000 to something else, but that didn't helped. Good think is that I have a workaround.

I also tried to run the same project with the same setup on my laptop, and there is no problem there. Soo most definitely something is messed up with my machine.

 

This advice is what helped me. Closing a backend api i had running in debug mode in visual studio 2022, was the fix. This 'backend api' project is totally unrelated to anything unity.

 

Same, Unity Editor loading hanged on Initial Asset Database refresh step because of backend project running in separate Visual Studio.
Unity project communicates with backend project via REST api, but only in PlayMode.
No editor script calls to backend project.

 

I'm also stuck at Initial Asset Database Refresh sometimes. To fix this I delete all temporary files (Library, Temp. project.sln etc. Then I make sure all unity related ***.exe are closed via Task Manager. Then I make sure no Visual Studio is running.

That usually fixes it.

Not sure about the cause of this issue, but Unity.Licensing.Client seems to be stuck for some reason. I have to always terminate it via Task Manager, when this happens

 

I was having the same issues with getting stuck on initial asset database refresh, I got to this rather old thread here via google search. Completely Closing my Visual Studio which was open for doing some other completely unrelated task to Unity seemed to have solved this problem which persists as of now in Feb 2024.

Thank you all who have taken the time to write about this issue.

 

WOW! That was it. I always have VS open for other projects (backend, for instance) and I had never noticed this was the issue. Thank you so much, this has been bugging me for so long, I've tried so many things to no avail.

 

Might be worth adding a solution that worked for me, although it takes a bit of time for the reimport:

1. Delete the library folder within Client and near assets.
   
2. Reopen the project via Unity launcher/hub.
   
3. Wait a nice long time while it all reimports.

 

I did this, but it didn't fix the issue. Anyone knows what else to do? I have uninstalled Unity Hub and Editor, completely deleted the project and redownloaded it from the repo. Still the same. Stuck on Initial Asset Database Refresh!
