Any workaround for "Crash near ___pthread_kill on non-Xojo thread"?

It happens too often last time.

It was happening for me every couple of hours with 17rX, but has gone away entirely with 18r1. Make sure you clear your Xojo cache (in ~/Library/Caches/Xojo/).

Cache clean doesn’t help for 2017R3

At one point there was a bug where if you closed a window while a thread was still running, a crash occurred. Could it be of the same nature ?

are you using any plugins or declares?

Using MBS. Crashed the Xojo itself

See if you can disable the functionality that uses the MBS plugins, I know it’s going to be hard, but most crashes.
