I got this on Reaper (6.64) when updating to 7.01. Unfortunately the backtrace doesn’t show a lot to me. Is this something I can cause or might this be some bug? Unfortunately no stack frame on any thread do show code of mine.
I haven’t tested this myself, but from the issue description, I think this issue may be fixed in 7.0.2 by this commit:
Please try updating and check whether the problem persists.
7.0.2 fixes the issue. Thanks!
