According to your testing, does the issue occur with ONLY Immersive Portals mod and Farbic API?

No? Just Immersive Portals. Farbic?

Describe the issue

Any experimentations on my end were done on an expendable copy of the modpack.

I've looked up exceptions in server tick loop and tried finding a dimensions folder by using NBTEditor. On an expendable copy of the modpack, I added the dimensions folder manually prior to creation, then added a folder in it titled immersive_portals, then added a file within that file named alternate1.

The posted error is from an untouched and downloaded directly from Curseforge and the error is from it the attempt to create a world. Again, this error only occurs with Immersive Portals added. In addition, if I load a pre-existing world that has been generated with all but Immersive Portals, then add Immersive Portals, the crash still happens. Without Immersive Portals, the game loads fine, if slowly, but I accept that in my quest for poor choices.

I'm starting to learn a bit of coding in college, this would be neat to learn, but it's also a hobby that I blunder with to make little or big modpacks for fun. I'm not very experienced.

Thank you very much for your help, lessons, and solutions! :)

Too many characters.  Files shared above.

You have Serene Seasons in the pack which is a known incompatible mod. Id start with disabling Serene Seasons and any addons/fixes for it and see if the state of the pack changes.
