Comment 1 tomtomtomreportingin 2021-10-18 20:02:22 UTC 
I've experienced hard crashes on three different occasions when starting a stroke in beta 2, but I haven't been able to get a backtrace yet...
Comment 2 Dmitry Kazakov 2021-12-16 12:21:54 UTC 
The backtrace looks like a duplicate for the memory corruption I fixed right after the release of Beta2. The fix is included into Beta3.
