So, I'm playing on my mod, I create a new world, it says "Preparing for World Creation", then goes to "Saving" and crashes. I've checked a lot and searched around, I found many results, but none helped, I tried reading or finding the crash report but I couldn't find the reasons. I'm not that good in reading or knowing what the cause of the crash is so I'm clueless too.

If you know what the problem was please tell me, I'd appreciate it.
