Hi I am also having the same problem with Kernel 5.8.0-45.51.
The workaround posted above fixes it for me too.

I keep getting this error when entering my password: "cryptsetup failed, bad password or options". I was somehow able to fall back into some shell while booting and it seems that any characters I type show up as diamonds "♦", except for the numbers. I also came across this thread which talks about a similar problem https://askubuntu.com/questions/1220022/keyboard-types-only-numbers- while-letters-are-typed-like-diamonds Switching back to 5.8.0-44 fixes the issue for me. I'm currently on Ubuntu 20.10 Would be happy to provide more details. Thanks!
