So it all loads up but when i press multiplayer it then says logging in , Waits for a few seconds and then Minecraft dissapears . It does not even open .​

The error mentions simply jetpacks. I would back up your world then disable the mod load your world then re-add it and try again.

You need to remove the jetpack from your inventory, ask the server owner for help.
