Crash Report (if applicable)

No response

Steps to Reproduce

Have both Connectivity and Immersive Portals installed, log in to server and get the error.

What You Expected

I expected both mods to be compatible-- And to be able to log in fine.

What Happened Instead

Both Immersive Portals and Connectivity are installed. Connectivity is CRUCIAL because it helps me get rid of "payload is larger than..." issues in a VERY bloated modpack.

When attempting to login to my server with both mods, i am faced with the "Internal exception: Java.Lang.nullPointerException: Cannot invoke “net.minecraft.network.protocol.Packet.m5797(net.minecraft.network.PacketListener)” because “packet” is null" error.
