Library\ScriptAssemblies\Assembly-CSharp.pdb: The process cannot accessg

I'm getting the same issue here, for the last couple of months since switching to 2021.2. Can be any project using Burst.

 

Crossposting from the other thread discussing the same issue:


I can quite confidently say that Burst version 1.7.0-pre.1 solved whatever caused this issue.

I tried to recreate the error by repeatedly commenting and uncommenting lines of code inside and outside bursted code, to cause a recompilation.

Tried this on 1.7.0-pre.1 about 50 times, not a single time.
Changed back to 1.6.3, closed and reopened the editor - got the error on the second try.

 

Another possible workaround that does the trick without needing to fully restart the editor, if the save method does not work >
Try creating a new script, then deleting that script.

It seems anything that can trigger "Reload Scripting Assemblies" will solve the error.

 

Seems to happen when I save my scripts. after a while, the editor doesnt compile and I have to restart unity; Problem goes away after that. Am using latest release from Dec 11. 2021 on windows 10 2021.2.6f1

 

This works. I updated to 1.70-pre.1 for 2 days now, not seeing the error.

 

I found that when this happens, Unity is recompiling although reading above no idea if this is Burst related, but tend to have it installed. Saving in Visual Studio seems to trigger a recompile rather than a switchback does (on older versions?), but then if you save again while it's recompiling you get this error. Wait a moment before resaves and it's all gravy.

 

Hi, I have nearly the same problem but I'm not using Burst on my code, Burst is used by Universal RP and the pdb file that cause the error is Unity.RenderPipelines.Universal.Runtime.pdb.
The error happen only when I pull code changes from GIT.
Really weird error but really annoying too !

Unity 2021.2.3f1
Burst 1.6.3
Universal RP 12.1.1

 

Happens to me every 10 mins requiring constant editor restarts.

 

There is another thread that Unity has responded to, sounds like they are hoping to have this fixed in Burst 1.6.5.

Can confirm that I am having this issue on 2020.3.26f1. Really annoying to have to restart Unity every 15 minutes.

 

Hi! I find this video and real help me, link

UPD: After upgrading to the latest version of burst, this error no longer appears

 

ive been getting this recently like totally not sure why

 

Are we going to see a Unity person chiming in here??

 

They already did on another thread, they have a fix they are working on.

I'm using 2021.2.14f1 and the issue is still there.
Recently I got this many times and every time I have to restart Editor, which slow down development a lot!

 

The issue has now been fixed in the Burst package 1.6.5 and later.

 

Just quit unity editor and unity hub and reopen them.

 

Unacceptable.
