So, if I’m reading this right, you updated to Fedora 41 and now you can’t unlock the LUKS volume upon boot. Is that correct?

Then you did a bunch of stuff but described it so incomprehensible (and possibly repeatedly?) I have no idea what you did. 

And now you are asking if you can remove the encryption. 

First off, you would need to be able to decrypt the LUKS volume to change the encryption settings. If you can’t do that, you’re stuck.  

But more importantly, have you tried booting older kernels in GRUB2 on boot? It’s possible (albeit unlikely) that the new kernel was built with broken cryptsetup binaries. 

Another thing to mention, I see a lot of people who come to my work’s help desk because they suddenly can’t unlock their LUKS volume on their laptop. Most often it’s a typo, or they typed their login password instead of the LUKS passphrase  Sometimes it’s a broken keyboard. Other times it’s because the keymap isn’t the same as before. Very rarely is it because some corruption broke it. 

You should make sure you’ve tested all those possibilities. Also, if you can boot off a live image, you should be able to unlock the volume using cryptsetup or even a graphical tool like GNOME disks.
