Question Burst 1.6.0-pre.2 fails to link on fresh Windows 7 setup with permission denied on reading pdb

Hello,

When trying to open freshly checkouted Unity project on Windows 7 which has Burst 1.6.0-pre.2 in their dependencies the editor goes into safe-mode, spilling several pairs of errors each moment until closed.

Code (CSharp):

1.  
2. lld: error: permission denied
3. E:\\The Game\\Temp\\Burst\\burst-aot8164fott.nqt\\8941e6cf64255ec70e3ca9bc3661e414.pdb: Stream Error: An I/O error occurred on the file system.
4.  
5. While compiling job: System.Void Unity.Jobs.IJobExtensions/JobStruct`1<Pathfinding.Jobs.JobCopyRectangle`1<System.UInt32>>::Execute(T&,System.IntPtr,System.IntPtr,Unity.Jobs.LowLevel.Unsafe.JobRanges&,System.Int32)
6. at <empty>:line 0
7.  

Code (CSharp):

1. ected exception Burst.Compiler.IL.Aot.AotLinkerException: The native link step failed.

The project in question works OK on other devs systems (all of them Windows 10)

When using explorer to navigate into:

E:\\The Game\\Temp\\Burst\\burst-aot8164fott.nqt

I can see the *.obj files in place, but there is nothings with *.pdb extension

 

The second log should start with "Unexp" - missed in copy-paste - I am unable to edit oryginal post because of SPAM projection (wtf?)

 

Did you manage to solve this problem?

 

Maybe it will help:

P.S. - I got similar errors, but I can not check whether the update will help,
- while I'm still struggling with another bug 2021.2 beta
And my package manager looks like this:

PPS sorry for google-translate

 

Upd: It's really WORKS
-Burst 1.60 - solved this problem with errors in the console.
