This did help with the initial issue and I believe there is only one issue left, that being my metaspace allocation, the server refuses to start OR crash, and loops until I manually stop it, sorry for the hassle.
New log: https://paste.ee/p/TuDVr
Trying to start an Aternos minecraft server, but when trying to start the server, it keeps crashing, when checking the logs, there are 6 warnings saying just about the same thing, this is my first time working with Aternos or modded online servers altogether.
This is the paste for the logs:

Sorry!
