I'll contribute a thought -- FDE means the whole partition is encrypted so decrypting it may not be possible without quite a bit of manual effort.
While I know Bitlocker can in-place encrypt and decrypt on Windows, I don't know how this works and haven't seen the same thing on Linux. For reference, I have had FDE on all my Arch boxes for a decade and am not aware of any easy method.
A quick google shows that people agree on Ask Ubuntu.

Likely the easiest path here is backing up your items somewhere and starting a-fresh. There's a utility to easily flash on this post

Thanks for the response. I don't care about the encrypted information, as I'm just experimenting with the phone, so I'm okay with everything on the phone being erased.

I've been trying to work through that very post you mentioned, but the phone is different enough from a Linux PC that I'm not sure if my phone is detecting my SD card.
