Hi there,
I have recently gotten into very basic modded minecraft playing. I have been dabbling in all sorts of mods, without truly understanding all of the whole "situation". Recently I have been struggling to get into my modded survival world with the error message consisting of the information below. Please keep in mind that only my modded survival world has been struggling with this issue. All other worlds of mine, which are all creative, have been working perfectly fine with no issues. Any help on the matter would be greatly appreciated Thanks in advance.

I would most definitely not mind using spoilers in the future, if that is what is preferred on this website. And I do, in fact, have backups, I probably should have thought of that in the first place. I also read all of the additional links below your comment - very helpful indeed. Thank you for your assistance.
