Thanks.  It seems you show two different crashes here?

Anyway, the second one is due to a known bug in treesit.c, which was
fixed 1 day after you updated from Git.  So please update again and
rebuild.

Not sure what the first crash is about, but it sounds like Magit
triggers some kind of auto-revert, and that hits an assertion in
insert-file-contents.
