As title says, project runs perfectly on the editor, but on some Windows machines it crashes with the following errors:

Seems to me like almost everything involving signals, super classes or resources are bugging out. Anyone had similar issues?

To make it clear, AudioLibrary is the following resource:

extends Resource
class_name AudioLibrary

# Engine Audio
@export var audio_engine_zero_gear : AudioStream
@export var audio_engine_first_gear : AudioStream
@export var audio_engine_second_gear : AudioStream

    To anyone running into the same issue!

    I got it fixed by going to Editor -> Manage Export Templates:

    Set it as following (Export templates were also already installed and ready to use) and pushed Download and install again, effectively replacing the templates I had.
