The encryption defaults changed sometime recently.
The defaults cryptsetup command I had in a script stopped mount my encrypted filesystem until I did a bunch of research and found out what parameters needed to be specified to match the prior default.
If you want to try what I found out reply and I can boot up the encrypted machine and see what parameters I needed to add.

Thank you for your suggestions.
Keyboard does not look like it is the issue.
I also tried to start the fedora rescue selection, but it also required the entry of the LUKS passphrase (Curiously, while a normal release starts with a different gui and stops asking for the passphrase after 4 or 5 attempts, the rescue selection just keeps asking for the passphrase ... maybe forever.)
So, I decided to see if I could get the DVD drive to be recognized by the motherboard. When I put a DVD into it and executed from Maintenance Mode: cat /dev/sr0 nothing is produced. The media server has been quietly sitting in a corner for years. Anyway, with a twice over with my small air compressor making sure I manually opened the DVD drive and clearing any dust, the system then recognize a DVD and I could do an installation: installed linuxmint-20.3-xfce-64bit.iso then installed Fedora-Xfce-Live-x86_64-41-1.4.iso over the linuxmint installation but kept the /boot/efi directory so that the installation did an efi installation (not bios). I assume this is a trick that is not known by many and as my original email said, It was just chance that I guessed it might work.
While there was some stuff in the original /home directory, all of the media was on other, non-encrypted drives which I've now been able to mount in this new installation. Thanks again.

Early in Maintenance Mode I tested the keyboard and typed in the passphrase, twice, and it appeared on the screen correctly.
Just to be thorough... On the graphical login screen see if there's an icon for choosing keyboard layout/language. It is possible for the command line (purely textual interface) to be different from the graphical interface.
You can't remove disc encryption without re-writing every bit of data stored on the disc. When using an encrypted disc the system is decrypting the data on the fly, it's always encrypted on the disc.
Are you sure you want to do that, or simply access the encrypted data?
Of course, when it comes to updating an old installation of something with a new version of something else, there is every chance that the old encryption scheme isn't supported any more, so you would have to re-encrypt the drive (or just decrypt it, if you don't want encrypted contents any more).
You should probably be booting from something else, and something that's compatible with the original encryption scheme, to do this. I wouldn't risk trying anything that was going to decrypt in-place when its running from itself, well not if the OS is encrypted. I'd be more confident about doing that if it's simply user data space that was encrypted.
