Does not detect whether in game, terminal spammed with Bad Address

[JonathanBrouwer]

Among us starting is detected, however, the terminal is spammed with

error: process_vm_readv returned -1 instead of 4 (Bad address) address=0xfffffffffcff00ff 
error: process_vm_readv returned -1 instead of 4 (Bad address) address=0xfffffffffec47f54 
error: process_vm_readv returned -1 instead of 4 (Bad address) address=0xfffffffffec47f54

error: process_vm_readv returned -1 instead of 4 (Bad address) address=0xfffffffffcff00ff 

And the application always says I am in the menu, even when I join a lobby.

Is the S in the among us version important here? If it is, can I revert to the regular version somehow?

Am also Manjaro, installed from AUR.

Did you start CrewLink with crewlink or crewlink-launcher? I get that problem with crewlink but not crewlink-launcher. Although using the crewlink-launcher doesn't work anyway.

I get the same thing when running the Steam game with Proton on Pop!_OS 20.10
I don't have the AUR so I used the .appimage provided in the releases page and ran with the commands listed there
