crashing after latest update to bedrock.

very recently bedrock get a new update which is great, this update "fixed" bedrock switch version, it did the opposite. i had no problems with the game until now, i logged into the game to play and it immediately closed because of an error and it did this 3 other times right after. so when i finally get into the game and it doesn't crash i find out that 2 mobs i had at my base as pets are gone. my rare blue axolotl that took me hours to get and a goat, both were named so they did not despawn, they did not die because they were in safe closed off buildings. before the first crash i was checking on them and they were fine both of them were just minding their own business and after the crash i find out they are gone and i can't get them back. i'm sorry but i am seriously upset over this i lost two of my pets because of game issues. in case it hasn't been figured out the bug is that the game was working fine now i can't even open it without risk of a several crashes.
