runClient failing with error "finished with non-zero exit value 1, 1.16.5 mod

I am running a mod with 50+ elements. When I press "run client" or "run client and server", instead of Minecraft loading successfully with my mod, the square in the bottom-right hand corner turns right for a few seconds, then turns left. I am using an Asus ZenBook 14.

When I check the console, this is what I get: https://pastebin.com/RbDjZAcF

Help?
