Server Keeps Crashing Because of Datapack

[I am not using Forge, I am using PaperMC] I installed a datapack and resource pack from https://www.planetminecraft.co…k/capturetheflag-5128931/ and used it. When I started using it, the server started to crash to the point where I couldn't even do anything. Joining the server results in an Internal Server Error. Here is the log https://mclo.gs/DjySVen
