I cannot reproduce this bug with my local build, but the above snippet of dump
file looks like LibreOffice's macOS accessibility code is trying to query a
LibreOffice object that has already been deleted.

I recently committed a fix for a similar "macOS querying deleted LibreOffice
objects" bug while working on tdf#158914. That fix will be in the upcoming
LibreOffice 24.2.4 release (expected release is within the next week).

When LibreOffice 24.2.4 is released, can you see if the bug still exists in
that version?
