Cannot Set Keybinds/Push to Talk

I run Discord stable 585344 (8b1d591) Host 1.0.151 x64 Build Override: N/A Linux 64-bit (7.0.0-28-generic) under ZorinOS OS 18.1 Core, and noticed yesterday, just after a new Discord update, I can no longer set keybinds, and Discord no longer remembers my login information from session to session; makes me log in every time I open it, even if I haven't restarted my computer.

Every time I've tried to set push to talk, it'll poll for a keypress, but doesn't actually accept input. I have no option other than to cancel out of the prompt and give up on using push to talk.

This is true for *all* keybinds, though; not just push-to-talk. Literally none of them can be customized. I was thinking maybe this was just an issue with app focus, so I checked my OS settings, and everything is default, no settings have been changed since Discord updated.

I did recently need to run fsck to fix a corrupted uefi table, but I'm pretty sure that I was able to continue using discord for a day or two before I noticed problems, so I doubt the two events are correlated.

I've not yet tried to uninstall and fresh-install Discord, but I have power-cycled my computer and the issue persists.

Update: I have uninstalled (everything, even user settings), restarted, and reinstalled. No dice. Discord still doesn't poll my keyboard properly when setting keybinds, and that's persistent across sessions, reboots, and fresh installs. Weird thing is, text chats still work without issue, and I can use my keyboard normally; just not in Discord's settings.

Good news is Discord has been logging me in automatically since my fresh install, so I don't think it's a directory permissions or access to local user settings issue.
