I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Older Solution: Use Proton 5.13. Others still seem to experience this issue with Proton 5.13 however. Results may vary.

Game works mostly fine when in mouse-only mode, but keyboard input very rarely works. Seems to happen consistently on Proton 5.0 but harder to replicate on 4.11 (may need more confirmation on whether or not this is just a fluke), but I so far haven't been able to replicate it at all on Proton-5.9-GE-6-ST as suggested here. Other Proton versions with wine-staging's rawinput patches might also resolve the issue.

Workaround: Consider using GloriousEggroll's proton-ge-custom, avoid alt+tabbing or switching focus while the game starts up.

Reproduction

1. Launch Among Us with Proton 5.0
2. Open Settings
3. Set "Controls" in the "General" section to "Mouse+Keyboard"
4. Launch a freeplay game on any map
5. Keyboard input may or may not work here
6. Alt+tab out of the game and back in
7. Keyboard input definitely shouldn't work here.

Alternative reproduction method: Launch the game, alt+tab a bunch until it starts up, and the keyboard input might stop working. Switching workspaces instead of alt+tabbing can also trigger it.

The Player.log in the game's AppData directory suggests the keyboard problems stems from Wine/Proton's interaction with Unity's new Raw Input system (RI.Hid):

Might become an issue as newer Unity games start using this input system.

If you think your GPU should support Vulkan, check that you actually have Vulkan drivers installed. Search for instructions on how to install Vulkan for your distro + GPU.

If, for some reason, you want to forcibly reproduce this issue on your system that has working Vulkan, you can set your launch options to VK_ICD_FILENAMES="" %command%. Only do this if you want your game to crash.

Ultimately this symptom isn't actually an issue with Wine/Proton but rather a hardware/driver issue, but I've posted it here since it's fairly common.
