Vanilla+ Server Crashes Upon Updating

[bright blade]

Good evening! I'm currently hosting a server for me and a dozen or so of my friends. I've been trying to update it from version 1.21.4 to 1.21.5 to no success, the server crashes whenever I switch versions. I'm running paper software and a handful of datapacks. I tried reading the logs time and time again, but I just can't make out what's causing all this trouble. I've asked for help on the Exaroton and PaperMC servers already, and I was told it'd be a good idea to come ask for assistance in here.

I've taken a glance at your log. Here are some potential issues I found!

• It appears Terralith was uninstalled incorrectly. Biomes must be removed from the level.dat - see /faq Removing Worldgen Packs.

How was my response? Let me know!

you need to update the datapacks too, not just paper
