CRASH when trying to create a world from Marketplace

Hello, 

I've got a bug that not allows me to create worlds bought from Marketplace. When I try to create these worlds, it shows: "Saving resource packs" and after a while kicks me back to world creation menu (where I can't do anything). When I thy to go back to world list, Minecraft crashes. This affects all versions (sometimes it allows me to create a world, but rarely) from c. a. 3-4 months.

Best regards,
