Wheel and Pedals not detected in Proton 5.13-2 (works in 5.0-10)

Problem: Wheel Controllers (Logitech G29 Wheel and Feel VR Pedals) not detected in-game.
Games: Project CARS 2 and 3 // Assetto Corsa

Repro:
Fresh default install of Manjaro 20.2 following these steps:

1. Boot Manjaro 20.2 Live CD / Install on a formatted SSD (no previos OS or info on that disk) with Proprietary Drivers (nVidia)
2. Run a full system update (only 1 package updated at the moment of the test on December 6th 2020)
3. Launch Steam, log in.
4. Enable SteamPlay with latest Proton Version (5.13-2)
5. ReLaunch steam
6. Install the game (any of the listed above)
7. Launch it and try to configure the controls.
8. Game won't detect any input.

If I go back to SteamPlay version and force 5.0-10, Game works perfectly and detects the controller input in all games.
Going back to 5.13 WILL NOT fix the issue.

No source files, tests, or entry points are named. Start by reproducing controller detection in Project CARS 2, Project CARS 3, or Assetto Corsa with Proton 5.13-2, then compare behavior with Proton 5.0-10 on the listed Manjaro setup. Done means the Logitech G29 and Feel VR pedals are detected in-game under 5.13-2.
