Attach Debug to Unity with no Play mode blocks Unity anyway

Unity is NOT in play mode.
I hit attach to start debugging from Visual Studio 2022.

What has never happened and happens now is that Unity is stuck. Irresponsive. I can’t click play or anything.

I restarted the whole computer, Unity, Visual Studio. Still happens. But it didn’t happen before. How do I fix this?

When I click stop in Visual Studio It gets slow and I get a popup. "Debugging is being stopped but not yet complete. You can force … "

Ok. So the fix for me is to open Debug /windows / Breakpoints. Delete all breakpoints.

Seems like there was a broken breakpoint.
