Just recently when I try load single player in Tekxit 3 it gives me the message that Minecraft has crashed but says the mod the caused the crash is unknown. Previously it said the the Custom Main Menu mod might have been to blame so I went ahead and deleted it but now it says the cause is unknown. I would like to try deleting Tekxit 3 and reinstalling it again to get fresh files for all the mods (and get Custom Main Menu back) but I don't want to lose my worlds! Any help would be great . (I can't access any world). Here is a copy of the crash report: https://paste.dimdev.org/owuxutoxal.mccrash (Image is not from my crash but has the same information except the link to the crash report)
