Referring to the log, the world is still loading - just wait some more time
Even with the not responding message, the game/world is still loading in background
Maybe create a new modpack instance and start with cyclopscore, commoncapabilities and Integrated Dynamics - try different builds until you find a working combination - then add the rest of your mods
There are too much client side mods there
Like
dynamiclightsreforged
FpsReducer
embeddium
BetterModsButton
sounddeviceoptions
mousetewaks
etc
Maybe switch to a pre-configured modpack - most of these have a server pack - use such a modpack as working base
Add crash-reports with sites like https://paste.ee/ and paste the link to it here
Looks like the server does not have access to the directory - make a test with another directory
Also, use Java 17 instead of Java 18
