Describe the bug

If I install GE-Proton-10-4 and have "proton-cachyos-latest" set as the default wine version in settings, a newly installed game will pick GE-Proton. Other settings, such as disabling game mode work fine.

Add logs

Steps to reproduce

  1. Install GE-Proton-10-4
  2. Ensure Proton-CachyOS-Latest is set as default in settings -> game defaults
  3. Install a new windows game

Expected behavior

The new game is installed with Proton-CachyOS-Latest is set
