Debugger unable to Transition

[TonyValenti]

Description

Since moving to .NET 9.0, we've been having issues with debugging.
With one of the issues, we consistently get messages saying the debugger is unable to transition.
I've started asking for process dumps when this happens.
Can I provide those to someone who can analyze them?

Reproduction Steps

Run our app and debug it. Sometimes it happens, sometimes it doesn't.

Expected behavior

I should be able to debug without issue.

Actual behavior

Sporadically we get debug errors requiring us to terminate the process.

Regression?

Yes. This didn't happen in .NET 8.0.

Known Workarounds

None.

Configuration

.NET 9.0 on WINx64

Other information

Our app is highly concurrent.

Is there someone I can provide process dumps to for analysis?

What type of app is this? I'd open a VS feedback ticket (https://developercommunity.visualstudio.com/dotnet/report) and add a link here - that way your dump gets handled properly for privacy and such.

@TonyValenti did this keep happening?

[TonyValenti]

Yes. We have all kinds of issues debugging on .net 9.0.
I'll try to attend to this next week.
