Minecraft is always crashing, what can I do now?

I'm currently a supporter on a Minecraft server.

There's its own Is and the Spawn (at least that's important for my problem).

If I'm on my self-built is, everything is ok but my Minecraft always crashes as soon as it tries to render the spawn.

I play with LabyMod incl. Forge in version 1.8.9.

Since I've had this problem for a while, I thought it might be due to addons from LabyMod. When I uninstalled my recently downloaded addons, it worked again. However, it crashes now again. Furthermore, it only happens on this server.

My idea would be that there are certain blocks that my MC can't load, but unfortunately I'm unable to read the error code correctly. Maybe one of you can help me (error code stuck at the end)

Kind regards
