STR:

1. Create the new track and create a new clip in it
2. Start recording (make sure that you are recording to the same track)
3. Try to simultaneously do the following: stop recording (Spacebar) and click on the first clip's handle

I tested this with @vsverchinsky Vitaly's branch build: audacity-win-3.1.3-alpha-20211119+d998117-64bit

Testing on W10 I get no crash with this build - I do get the crash with 3.1.2
