Frequent segfaults when creating symbols and going back to schematic editor

Description

I'm creating symbols and editing a schematic and I get a segfault every few minutes.

The stack trace looks like #15977 (closed) but that was resolved in Sonoma 14.1. I'm using Sonoma 14.2.1 on an Apple M1 Pro MacBook Pro.

Abridged stack trace:

0   ???                           	               0x0 ???
1   _eeschema.kiface              	       0x10dc52044 ACTION_MENU::OnMenuEvent(wxMenuEvent&) + 2416
2   _eeschema.kiface              	       0x10dc895b4 TOOL_DISPATCHER::DispatchWxEvent(wxEvent&) + 2084

Steps to reproduce

I don't have a reproducible sequence of events yet but the basic sequence is:

Edit schematic
Tools -> Symbol Edit
Edit a symbol
Tools -> Update symbols from library

Expected behavior: symbols are updated

Observed behavior: immediate crash
