hey there, for a strange reason, I cannot login into an endeavourOS system, even having the right credentials and changing the password from the root account. root login and password work fine, but the regular user doesn't. for a reason the system rejects every password I type, even if I used passwd to change it from the root account.
note that it was working fine before, but after updating, it stopped working.
any ideas on how to fix this?
