Hello, I tried already several solutions, but without closure with this problem. My Controller stops responding out of the sudden in several Steam Games. And yes, it's only Steam Games. I played games without Steam and they worked like a charm without issues.

The things I did:

• Using USB-Cable or tried with WiFi Stick
  
• Reinstalling the Controllerdriver
  
• Updating the Controller
  
• Checking Controlls on Windows and Browser
  
• Checking Controllsetting in Steam
  
• Using Win11 instead of Win10
  
• Using different USB-Port
  
• Using different USB-Cable
  
• Restarting Game and Steam
  
• Enabling / Disabling Controller Settings in Steam

I hope someone can help me. I found nowhere a solution so far.
