Source Code, App & CrashDump : check at https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1331331

Repro steps:

1. Copy App to machine
2. Run dnSpy.exe
3. Drag any .net assembly to Assembly Explorer( or use Ctrl+O, select any managed dll)
4. Choose the assembly in Assembly Explorer, on the right side, right click and select Edit Assembly Attributes (C#) item)

Expected Result:
It should decompile the assembly

Actual Result:
App has stopped working window displayed

Findings :
This app is targeting .net5 by default, this issue occurs when we run against net6, it is not repro when we use .net5 runtime.
When we observe call stack, it looks exception occurs in ProfileOptimization.StartProfile method, when it calls coreclr!GetCLRRuntimeHost

@jeffhandley Could you please help to take a look on this to see if this belongs to system.runtime?

[Junjun-zhao]

Still repro this issue on latest 6.0 Preview 5 build:
Windows 10 RS5 X64 + 6.0.100-preview.5.21280.1: Fail

@jeffhandley @pgovind @tannergooding Could you please help to take a look on this to see if this belongs to system.runtime? If no, could you please help assign ? Thanks!

[Junjun-zhao]

@jeffhandley @pgovind @tannergooding
We are in Preview 5 release validation now, and sign off date is before noon of 6/4. Can you help to check and see if it is a blocking issue for Preview 5?

[tannergooding]

This looks like it might be a runtime side, rather than a library side issue (based on the exception coming from coreclr).

@jkotas, do you know who the right owner is for this?

[jkotas]

This is likely regression introduced by #48326 . cc @kouvel @noahfalk

The timed StopProfile() doesn't seem to be adjusting the state appropriately, so previously the profile may be written twice, and after the change above that would be problematic since it expects correctly that the profile is only written once. I'll prepare a fix.
