Minecraft Crashes As Soon As I Log In

Hello;
I have the Problem, that, as soon as I log in as my main account (lv 83 Archer) Minecraft freezes and then crashes sying "Internal Exception: io.netty.handler.codec.DecoderException: Java.io.IOEexception: Packet 0/36 (ki)vwas larger than I expected, found 3 bytesextra whilst reading packet 36".
I'm currently in the Restaurant doing the quest "The Envoy Part I".
I can't type anything before it freezes, thus /kill is not an Option.
Is there a possibility to get me away from that place e.g. if there's a mod/dev or do you have any other Solutions (e.g. get a better Computer).
Any help would be greatly apprciated.

 

Try playing with 1.9-1.12.2 vanilla Minecraft.

 

Sounds like you're using either 1.13 or a similar version to try to log in. Using a version between 1.9 and 1.12.2 should resolve the issue, although 1.12.2 is the most recommended one

 

I'll try it out, thank you very much for your quick Responses ^
