Sloth

I have been trying to put together a pack for my friend and I. I have never used fabric before but it has mods I would like to use that aren't in Forge. I don't know what is causing this error. I have deleted some mods I thought could be causing the issue and it still gives the error. This is the link to the error log, https://pastebin.com/g7NtV4Ps. Thank you ahead of time for support. I am not well versed in reading logs or Java.
