Crashing if i switch lobbies

[Blobaapie]

I used badlion client for a long time and didnt have any problems using it but it just missed a couple mods i needed. So i switched to skyclient and downloaded a couple mods and set it all up. The first few days of using skyclient everything was working and it was nice. Since yesterday whenever i switch lobbies my minecraft just crashes. Please if someone knows the problem TELL ME cuz it is annoying.
