Hello, I have the same issue.
Typically it happens when I’m in playing mode, like just playing 20 minutes for fun and changing my preset every 3/4 minutes to explore my sounds.
Reaper suddenly crashes. My Reaper project usually has only the guitar track for this purpose, and it doesn’t stress my computer hardware at all.
My buffer sample is 48 or 64 when playing live, and I don’t want to higher my buffer sample even more.
It’s better to have an auto-save feature in the DAW when it happens…
Any fix is planned for this issue?
Thanks in advance!
