ok nervermind then i really dont know ... what modpack are you trying to run ? And if its Custom what a Mod list would be helpful.

Not an Expert on DataPacks but i would try to remove all DataPacks (world/datapacks) from the server and put them in one by one to find the one that causes the issue. And Backup the World just in case.

This Line seems to cause it. [29Mar2023 15:03:31.633] [main/WARN] [net.minecraft.server.Main/]: Failed to load datapacks, can't proceed with server load. You can either fix your datapacks or reset to vanilla with --safeMode

I Tried using readNBTShareTag() & getNBTShareTag() but don´t know how they work... Code:
