Those EXT4-fs write access unavailable errors look spooky. Should probably do some standard Linux FS testing (fsck)

I’ve not had to recover anything from a raspberry pi SD card, but in the case you start from scratch - and considering it’s upset at write access - you may be able to plug it into another machine and at least salvage bits of its configuration that way.

I use mealie, but an older version which still has its recipes public. Still waiting for that to be an option on newer versions.
