I run a forge server with a bunch of mods that randomly started having extreme tick problems. I have no clue on how to or where to start reading this crash report, so some help would be greatly appreciated. I've tried changing max tick time to -1 in server.properties, and this did stop the server from crashing, but there's no point in playing as every action in-game takes several seconds to execute.
