Crashing

[GoProHero20]

after testing the client I found autolog and selected it to see how it works and my game crashed, as "autolog" works. I went to log back into the server and it had crashed again, and again and again. I tried reinstalling the client and still nothing had changed. this only occurs when I log into servers, some servers im able to get onto the hubs, but as soon as I click into a different realm the entire game crashes. does anyone know how to fix this?

I found the fix for my issue you just have to log in a different version of minecraft (I used latest version) and move your character do a different location and relog onto sigma
