The Paradox launcher and game won't start on Xbox Game Pass.

If you experience issues with Games that use the Paradox Launcher on Xbox Game Pass, it can be a problem with your antivirus and ransomware protection software. 

To fix this, you can try the following:

1. First make sure you have no Paradox related processes in the background. You can check this for example via the Task Manager on Windows. 
2. Disable your Anti Virus live scanner functionality temporarily before launching. For example:
   1. For Windows Defender, this can be found under:
      Windows Security - Virus & Threat Protection Settings - 'Real-time Protection'
      
      
   2. For Avast, you can follow these instructions. It should be sufficient if you change the setting under: “Protection” - “Core Shields” - “File Shield” - “Scan programs when executing”.
