It says the cause is "Failed to load datapacks, can't proceed with server load. You can either fix your datapacks or reset to vanilla with --safeMode". I'm not using any datapacks but i think mods are considered datapacks too so maybe it's a mod that is causing this. I tried using the arg "--safeMode" but it didn't help. Here is the lastest log: https://pastebin.com/Wfz913qJ.
