Something happened with my account while trying to create world from my inventory in my account and now it says it has error -9 and says that will be resolved soon and if not to contact support. Also the mcpe version is 1.16.0.53  Beta but the newer is written because it couldn't find that version, also it is beta Minecraft.

Edit: When I restarted my game it crashed 1 time in the first second then I re started it again it worked normally and the error was fixed.
