Symptoms

I have a game-breaking bug in RDR2 during the Chapter 3 mission "Magicians for Sport". In the woods scene where I have to fight two bounty hunters, my mouse buttons suddenly stop responding and I can't throw any punches or block. It seems like a compatibility issue with how the game handles inputs during this specific scripted fight. My logs show these specific errors:

08ec:fixme:keyboard:NtUserActivateKeyboardLayout flags 40000000 not supported

0948:fixme:keyboard:NtUserActivateKeyboardLayout flags 40000000 not supported

Reproduction

1. Start the Chapter 3 mission "Magicians for Sport" and follow Charles to Trelawny's caravan.
2. Track the kidnappers to the woods using Eagle Eye.
3. Reach the camp and trigger the scripted fistfight with the two bounty hunters.
4. During the fight, the mouse buttons (left/right click) stop responding, making it impossible to attack or block.
