Description
This only occurs in my codebase and not the editor hotreload example that works fine, but I am getting linux_reload_workaround.rs:95 hot reloading should only be set once: true panics whenever I compile my code in my project. This has been going on for the past 8 months or so, but since August my temp solution of deleting the .godot folder no longer worked to fix editor hotreloading for that Godot Editor session. On Windows this hasn't been an issue, its only an issue for my Arch Linux system.
I linked my codebase in the discord thread discusing this issue https://discord.com/channels/723850269347283004/1375167369894432789/1375207827848564818 where there is also details regarding stacktraces and replacing linux_reload_workaround.rs with print statements. This is a Godot 4.4.1 stable project. To replicate, be on Linux, compile project before opening, open project and add a comment anywhere in the code base, and then compile again. End result is a panic in your console and the editor will no longer reloads your code.
This is the same error but with print statements add to the linux reload workaround script:

> is_hot_reload_enabled
> thread_atexit
