Log too big to be added - even zipped.

Symptoms

Game crashes as soon as a controller (tested with Vive wands or xbox 360 controller) is turned on. If they're turned on before the game is started, it crashes as soon as the game checks for input.

This also happens for games Onward and VR Trivia Battle

Switching to Proton v 3.7-8, the games do not crash when the controllers are active (but instead they have other 3.7-related issues like missing objects).

Reproduction

Start game, confirm that it responds to input from the HMD - and then turn on a controller. The game will crash. SteamVR and the Steam client remains unaffected.

No project files or tests are named. Reproduce the crash by starting Derail Valley under Proton 3.16-x, confirming HMD input, and activating a Vive wand or Xbox 360 controller; compare with Proton 3.7-8 and investigate the controller-triggered failure.
