We're having the same issue in our household with one of our PC's. All 3 PC's are identical except for graphics cards (1650 super, 1660 super and a 2060 super). Only one PC is affected and keeps having the "Internal Exception: io.netty.handler.codec.CorruptedFrameException: length wider than 21-bit" error comes up after about 30 second of gameplay on another computers LAN game. Swapping cards makes no difference.
The affected PC can host a LAN game and the other two can join without issues, but the affected PC cannot join games on any other PC or servers.
Ok, so it appears we may have resolved the problem in our situation.
Having three identical PC's really helped. I realized that graphics cards were not the only difference in these PC's.... they all have different external wifi adapters.
The PC that was having the issues has a Panda wireless PAUD5 adapter. I swapped it to a AC1200 wifi adapter from another PC and it was then able to join LAN games and servers without any problems!
Looks like problem solved.
I'm still not sure why this problem started as the PC was using the same wifi adapter for 4 years without a problem.
