Your error says that you're using DEV 1090

it shows the version from the name of the jar file, it does not change during automatic update
I verified the version with the /version slimefun command

If you verified can you put those screenshots on the main message?

I added a screen of log, can it be?

Can you give a screenshot of the output of /sf versions

but it's now showing version 1.20.1 because I was uploading a backup to the server - some plugins haven't had an update yet

The error shows that it's a purpur/paper issue with deserializing honey block data.
I had a look and found the corresponding issue: PaperMC/Paper#9823

It is supposed to be fixed soon-ish, have a look for purpur updates.
