FoolCraft : Forge 12.23.4.2760 : Pack Version Release 1.5.2 : Loading into a multiplayer server errors

I click on the server in my list then on "Join server". The world loads then within 5 to 15 seconds (98/100 times) I get kicked and Minecraft gives the added crash reports.

As I am not the server owner nor its admin there is not much I can do on the server side and I have been told that we are waiting for the new FoolCraft server pack to become available.

Any hints on

1. What I am doing wrong?
2. What can I do to solve this issue?
3. Am I just trying to rush things and need to wait for a pack upgrade?

Not very technical since I had my mini stroke so sorry if I waste anyone's time. I play Minecraft to take my mind of my other physical issues as it requires very little hand to eye co-ordination and I can get hints and tips from youtube to help me out.
Thank you.

It is a pretty outdated version, but the stacktrace isn't really indicating that an update should fix it.
At first glance it looks like some rendering/"performance" mod could incorrectly change the normal rendering behaviour.

The best approach would be to wait for the modpack to be updated with all mods. If AE2 is horribly outdated, it is pretty likely that this also applies to other mods and might already be fixed upstream.
