I'm getting this error on one of my .NET 8 app. I created SO post with an example of an app that causes this.

Fatal error. Internal CLR error. (0x80131506)

Hi!

Thank you for reporting.

Is this issue only reproduced in Tracing or Line-By-Line mode?

Could you please check if it's relevant for Sampling or Timeline modes?

I've tested in Tracing mode. Now tried it in Line-By-Line mode and saw the same error. But in Sampling mode the app was able to run fine and got a snapshot. But probably our QAs will not be satisfied with this mode :/
