Cant connect to worlds or servers, if i try to my minecraft crashes.

Hello, since the 1.14.6 hotfix today I cant seem to join my friends worlds or servers. My Minecraft crashes right after trying to join the server, and I'm stuck on the "loading resources" screen if I try to join a world. Please fix this so we can play Minecraft again, thank you. Apperently my sister can join the servers but i cannot. I dont know if this is my device or account. Please fix as soon as possible.
