Hello, I may have a solution. Nintendo switch controllers may connect natively to PC pretty easily, but most programs wont recognize it so you usually need to run another program to feed the inputs correctly. Having steam open in the background with Nintendo switch configuration on might be eenough, but I think BetterJoyforCemu will be able to fix your issue more reliably. It has a setting to run the controller as Xinput which will probably fix your issue.
