For a program that is years and years old and costs hundreds of dollars, BiaB sure crashes a lot!

Last night it gave me an error in the middle of work warning me to save before the app crashed (which I was able to).

Today, I've been trying to import a finished song into Reaper using the BiaB VST. The song generates completely (I get the green popup box) and then the BiaB VST crashes, taking Reaper with it. This has happened at least a half dozen times. I've restarted everything including PC, renamed files, tried opening new Reaper project, etc.

Pretty frustrating. These are just the two most recent examples.
I don't run both apps at the same time.
Windows 10
Reaper 2021

Kinda disappointed. Rant over.
