i believe i've found a relatively easy-to-perform fix that everyone should be able to do,
1. download the linux version from itch.io
2. extract **ONLY THE .pak FILE**, DO NOT EXTRACT THE .x86_64 file
3. go to https://godotengine.org/download/linux/ and download version 4.1.3 of the godot engine for linux (afaik this program was compiled for 4.1.2 but 4.1.3 still works and is the only version i've tested)
4. save the engine binary in the same folder as the .pak file you extracted earlier
5. rename the engine binary to the same name as the .pak file, only this time switch the extension from .pak to .x86_64
6. launch the engine binary, and the program should start! from my testing, audio seems to be fixed if you do this, although results may vary
