Password issues from day 1

I’m having intermittent issues when attempting to login.

My first attempt to use PopOS failed when I couldn’t decrypt after installation. Assuming it was my fault, I re-installed (clean) and managed to login fine last night and this morning.

This evening I try to login again and can’t get past the lock screen. Switched to the console and it let me login after a few attempts. Updated and rebooted now it says it’s a bad password when decrypting.

After the first attempt I kept the password text only so I can’t see it being related to the keyboard layout.

Are there any known issues? Online searches suggest the common issues don’t seem to match with what is happening here. I loved using it yesterday, but this is worrying if I get locked out after using it for a while.
