This won’t be helpful to fix your issue, but to explain - you can’t log in with your password because it’s asking you the root users password, which is not the same as your user accounts password (unless you’ve changed it). Under Arch Linux distros usually, when you install it will prompt you to re-use the same password as for your user for root too. Under Fedora and it’s variants (Like, Bazzite) usually root has login disabled because it doesn’t have a password set (which prevents anyone from accessing root as a security precaution).
To get into your Linux env you would probably have to use Chroot method - here’s an article that shows you how to do it: How to: Chroot into a broken system via live CD/ISO or alternate Linux system | TurnKey GNU/Linux
Note that you’ll need a bootable Linux ISO (I think just about any version or distro will do, unless your system uses Btrfs - then you’re tied to versions that have built-in support for that …like stock Fedora Workstation, for example) so that you can access the terminal and type in the commands.
