Trying to make a mod pack to play with friends but as I'm making a world and play testing it crashes and then gives me the "Errors in currently selected datapacks prevented the world from loading" message after I try loading it again. How do I fix this? crash report:https://pastebin.com/Z0Rhjk3k mod list:https://pastebin.com/ADXRFPQ3
