Whenever i try join my friends realm i am kicked out minutes if not seconds later. The error codes that appear are sometimes different and sometimes the same, they consist of:

-Internal Exception:io,netty.handler.codec.DecoderException:Badly compressed packet - size of (this is random each time) is below the server threshold of 256
-Disconnected (this one is very rare but i dont have bad ping or internet)
-Internal Exception:io,netty.handler.codec.DecoderException:Badly compressed packet - size of (this changes but is usually incredibly high) is larger than protocol maximum of 2097159
-Internal Exception:io,netty.handler.codec.DecoderException:java.util.zip.DataFormatExeption: incorrect header check
-Internal Exception:io,netty.handler.codec.CorruptedFrameExeption: length wider than 21-bit

These were the different errors i recorded in around about 10 minutes, mind you they were every 1-60 seconds intervals with me joining and being kicked out with the error. i have tried troubleshooting minecraft java and the installer, i have uninstalled and reinstalled the game and even removed it on my firewalls. i have also deleted all my antivirus. nothing has helped. this happened once or twice on a server but never as worse than on realms. its ruining game play and i have almost perfect ping and internet on my gaming pc. this has never happened before the last two weeks and it was fine for the first three days i joined the realm. id say half way through the third day these errors started happening.

Its making the game unplayable and i seriously don't know what to do. please help me fix this.

P.S i think my FBI agent is messing with me at this point.
