Error "fatally missing registry entries"

Me and a friend wanted to make a server with mods, so we chose all the mods that interested us and installed them both in Aternos and in our PCs. My friend doesn't know much about mods so I installed them. Now comes the problem, when I try to enter to see that everything is fine, I get the error of "fatally missing registry entries".

Server log: https://mclo.gs/ci925IB

Client log: https://mclo.gs/tXk9Q1Q

Also, if necessary, I leave the list of mods that I use

I hope someone can help me and tell me if it is a compatibility error between mods or if it is some installation failure.

Thanks in advance.
