DO NOT ENABLE any of the disabled animations. These are the root cause of multiple animation loops that can break the game, to the point where you have to delete your current save file.
This bug is called "busy hands", an animation loop that prevents the player from interacting with the action keys, except for movement. This bug can also and especially be found with vanilla animations. Try not to spam them.
If you are still unsure whether you have it or not, try to do any of the following:
- interact with objects or people
- use a weapon (you shouldn't even be able to see it when you select it)
- open your inventory
- drink/eat/sleep
- check your HUD in the bottom left corner
If you cannot do any of this, it probably means you do have busy hands.
The only possible way to, maybe, remove it completely, is to disable any extra activated animation that was previously disabled. You will also have to go back to a previous save where you are 100% sure that you don't have busy hands.
Certified DISABLED animations that bring busy hands:
- Opening/closing backpack and any option related to this
- Animation for skinning mutants
- Disassembling objects with Left-Alt pressed
- Picking up objects where you can see the hand movement
