Intermittent stepping behavior while debugging

[HitalloExiled]

Issue Description

Sometime when stepping some code, the debugger is just released like if F5 (Run/Continue) key was pressed.

Initially, my suspicion was a keyboard problem, but this occurs on two different machines.

Steps to Reproduce

It's an intermittent problem.
I am unable to reproduce the issue intentionally.

Expected Behavior

When pressing F10 (Step Over) it behaves like a step over.
When pressing F11 (Step Into) it behaves like step into.

Actual Behavior

Sometimes F10 or F11 triggers Continue.

What version of .NET is your project running under?

Version net9.0
I've been using this version since the first previews. I started noticing this problem in the last two months.

I noticed that the problem also occurs when using the UI buttons.

[gregg-miskelly]

This is a problem with .NET 9. The .NET team hasn't been able to figure it out yet -- when they try to add tracing the problem goes away. But I opened a public issue about it:

dotnet/runtime#109785

The only work around I am aware of is that if your project is something that can also target .NET 8 (or earlier) you could debug that configuration instead.
