[Probable race condition bug] Blender crashes on plugin startup

[ErickEM9]

Every issue should include 3 things:

1. i7-12700h, rx6900xt, nvidia rtx 3050ti (unused) - archlinux
2. a project is not needed
3. I expect blender to not crash, it crashes instead.

When I enable the addon blender crashes.
Therefore, in an attempt to discover the faulting component, I ran blender in gdb and as a result the addon works: i suspect the plugin loading code has an unidentified race condition.

Issue

The problem is blender crashes and it manifests when I enabled the plugin or simply start blender(while not running in gdb).

The issue is always reproducible when running outside gdb and never reproducible when running in gdb.

Steps to Reproduce

Install addon from zip file and enable it.

System Setup (Environment)

Archlinux: linux 6.12.7-zen1
Intel i7-12700h
AMD rx6900xt
nvidia rtx 3050ti (unused)
