Cinnamon lock screen wont recognize password after screen is locked

I have been having this issue for over a year now, maybe even two. It specifically happens to arch and arch-based distros. I have searched countless youtube videos, several forums, reddit, and ive even made a post in this very forum about it and i have no idea how to solve it.

The problem usually only occurs if i have the screen locked more than five minutes. Anything after five it wont recognize the password and the only way to log back in is if i reboot the computer and log in from scratch.

You're either running into a keyboard reset or faillock
Open a shell on a different VT (ctrl+alt+f3) and trigger the problem.
Check

faillock --user cpdf98 # use your actual username on the system

If there's a lock

faillock --user cpdf98 --reset

and try to log in.
In this case perhaps some cronjob/systemd timer fails on a sudo invocation or something like that.

If that's not the case the keyboard might have logically detached and reset to US qwerty, try a qwerty-safe password

It failed the lock screen login and i clicked the button that brings me back to the login screen and again the password didnt work. I hit ctrl-alt-f3 and it brought me to a terminal login (what it looks like when you have freshly installed arch but havnt installed a DE yet), and again my login didnt work.

The idea was to open a shell on TTY3 *before* you trigger the lock to give you an interactive shell to inspect the system.
But it's most likely faillock and not even necessary a bad sudo invocation (check your journal), there was https://bbs.archlinux.org/viewtopic.php?id=284070

On a formal note, please don't bloat the thread by posting full quotes without good reason.
