Minecraft freezes and freezes pc when i log in in my account

Hi, i have a huge problem. Minecraft windows 10 edition has always worked in my pc, but with the new aquatic update (I really don´t know if the update is the problem) my Minecraft freezes or stop working and sometimes it also freezes my computer so i have to turn it off manually. I realised that minecraft start failing when i log in in my microsoft account. When i don't log in, i can perfectly play. I tried to play in another pc, and the problem is the same. I hope you could help me solve the problem ASAP. Im from Costa Rica P.S.: Sorry if i made a gramatical error, or mispelled something. I don't speak a lot of english.
