Symptoms

For the release version of the game: controllers disappear if you enter the steam menu by pressing the system button or turn on room view by double pressing. The problem can be avoided by disabling vrmonitor and room view from SteamVR settings.

For the public beta version (elevenrevamp): the game crashes immediately on start up if the controllers are turned on, or if the controllers are turned off at start up, it crashes as soon as you turn them on. Disabling vrmonitor and/or room view has no effect.

When the controllers disappear in the release version, nothing is logged to error.log. However, when the beta version crashes, the following is logged:

Unhandled exception: page fault on read access to 0x00000000 in 64-bit code (0x00007fcdbd336ef0).

After talking to a developer of the game (and showing them this error), I believe that the two issues are related. They told me that they use this function to create the custom controller graphics.

Reproduction

Start the non-beta version of the game. Press the system button. Press it again to return to the game. Controllers are now gone.

Go to the game properties -> betas and select the elevenrevamp beta. Start it, and observe that it crashes immediately. Wait for controllers to sleep and start the game again. It now starts up, you see the table etc. Turn on a controller, and it will crash the same way as before.

This is the proton log file from running the release version and entering then leaving the steam menu so that the controllers disappear:

steam-488310-release.log

This is the log file from starting the beta version with controllers disabled, and then turning one of them on so it crashes:
steam-488310-beta.log
