Solutions

Workaround

What you tried to get the feature working

Updated from Godot 4.2.2 to 4.3
After experiencing the issue with 4.3, I added the line:
const DialogicTimeline = preload("res://addons/dialogic/Resources/timeline.gd")
to res://addons/dialogic/Core/DialogicGameHandler.gd
After running the scene with the code change, the error did not occur. I removed the code change, and the error did not occur.

Possible fixes

Any idea to fix the issue or a link to the line of code that might be the cause for this problem
