Symptoms

The Game works perfectly (did a complete playthrough) except when Nintendo Switch Pro rumble support is enabled. During rumble feedback the directional controls stop working, basically making this game unplayable (as you lose all control of the character).

With rumble disabled, the game works perfectly

• Switching between desktop/windowed works
• Great performance, not even any shader compilation stuttering (ACO was enabled)
• Nintendo Switch Pro controller support works (except issues with rumble)

The log is when trying to play the game with controller rumble enabled.
