thank you so much

Unity 2018.3.11f1 (64-bit) the problem was smooth

2018.3.10 problem

 

@okcompute_unity Yeah

Many thanks for your help

Çok Teşekkürler, Turkish

 

Unfortunately I have this problem as well, and it is not resolved in 2019.2.1f1. Getting a lot of theses errors:

Asset with guid '3a2d94c8977984b67984caeff9fa666e' and path 'Packages/com.unity.collab-proxy/Editor/Resources/Styles/CollabHistoryCommon.uss' is up to date, but does not have a valid target hash assigned to it in the GuidPersistentManager
Asset with guid 'fd3d7c275a0958b4fa0f26a0ee9b8481' and path 'Packages/com.unity.2d.sprite/Editor/UI/SpriteEditor/SpriteEditor.uss' is up to date, but does not have a valid target hash assigned to it in the GuidPersistentManager
Asset with guid 'd02b5650e6e0b4c45ab18d5a1d1fce97' and path 'Packages/com.unity.2d.sprite/Editor/UI/SpriteEditor/SpriteFrameModuleInspector.uxml' is up to date, but does not have a valid target hash assigned to it in the GuidPersistentManager

Around 20 of them. Any other solutions aside from uninstalling and reinstalling unity? Just started happening today and hadn't happened before this before.

 

@gflkidd Were you able to resolve why and how to fix these errors? I'm not sure it's causing an issue or not tbh...

 

suddenly i get this problem, this problem only in HDRP project.
whenever i am trying to open my project HDRP it shows like this.
I reinstall unity lots of time but its not working, I am trying in always.
pls help me..,

regards,

okcompute_unity

 

What happens when you reimport? Same issue?

 

I have this problem as well, and it is not resolved in 2020.2.4f1.

 

and a reimport doesn't work?

 

I have a similar problem with create new Project in unity 2020.3, 2021.1, but in 2020.2.2f1, 2019, 2018 no problem

 

I understand why the error.
I create "mklink" for "unity cache" folder from .bat file (because the disk C have low memory, old and slow speed, I transferred files to another local drive):

mklink /D "C:\Users\AntonioModer\AppData\Local\Unity\cache" "E:\Program Files\Unity_cache"

Ie the UnityHub does not work with "mklink" folders.
I maked default local "unity cache" folder on disk C, then new unity project created without error.

 

[RESOLVED]
I resolve error with mklink folder.
Issue in security folder parameters !
In my system on disk E WindowsOS set additional security options for folders.
I delete this security parameters (restore to default, like in disk C), and error is gone, mklink folder done fine with PackageManager.
So if this error is, you need set folder security access to all folders for PackageManager

 

Hi my tarball / tgz files are not uploading into my unity files when trying to import them,=. I am using a Mac book can someone help me with this please?

 

I'm still getting this error.



I've tried to reinstall both Unity Hub and Unity Editor, tried to clear caches, deleted the Library folder, set the folders permission to read/write, I tried to reset Packages to default, delete the Package Manager cache folder... I'm not sure what to do anymore at this point.

 

"permission to read/write" it won't help, i tried. You need to set the default settings. I had a special specific setting due to a Windows OS account via the cloud. I removed it and the error disappeared. Try updating Windows OS

 

Do you happen to have an apostrophe in your username? Like "Someone's Computer"? If so the workaround would be to rename your user account and remove the apostrophe, or create a new account.

 

This happened to me as well. It works on newer unity version, but then my shaders are a mess. I have looked into how to fix/update them, but they still look bad.
