@Sergey: This looks like a depsgraph thing. From the log:

There have been similar reports (see #57530, #57491, #57967 to an extend)
Seems hard to reproduce (e.g I cannot get the file from this report to crash)
Note: running blender with
--threads 1
seems to solve all these cases...The backtrace is a bit confusing (shows crash inside of pthreads library), but sometimes ASAN does indeed catch memory error. Here is backtrace which should give more clues:
P830: (An Untitled Masterwork)
@Sergey: please also check on #57530 [a couple of other reports have been merged to that one], might just be the same root cause...
@lichtwerk: Yes, those seem to be be similar. Sorry for posting a duplicate then.
