MCreator Error upon client launch or anything related to build

Last night, making my mod, I stumbled upon an error in my mod, something about it reusing a port of some sort, before this error happened, I made a dimension called Experimentation41 (resulted into Experimentation_4_1, yes, it's a LC mod), a block, a biome for it, and a feature for the dimension and biome. I then launched it and got this error (pastebin), I tried to delete my cache folder, let it run overnight, and everything build successfuly, I then regenerated the code, still ok, then build workspace base source files and all that, after that, I launched the run client and got the same error, I tried some build fixes (except the cache and gradle deletions) and still got the error, if anyone knows the problem that would be really helpful and great, thanks :D.
