Whenever I connect to a realm i was invited to, I crash. I admit that I spawned in a couple tools that had all level 1000 enchantments. I think that it crashed first when I broke a couple blocks with the enchanted pickaxe. However, it might have also crashed when steam updated because I had it open when I was playing minecraft. I hope that you can help me because I love to play on that realm and I want to begin playing again as soon as possible. Keep in mind that it does not crash when I start up minecraft itself. Its only when I connect it crashes. I do not have a contact from the owner of the server and I am a administrator on it.

Please help me!

Here is the report:
