Minecraft Forums

Hi all,

I've recently started playing minecraft again and have been using 1.11.2, alongside with the new launcher.

But it seems maybe a bug with me or the new launcher, that everytime I open up minecraft, I log into the skyblock server I play, and crash.

It first says not responding, then goes to a black screen and I have to force quit.

I have tried

- Updating Java

- Re-Downloading a whole new minecraft

- Deleting Java and Reverting to old version

None of these seem to work, I am still crashing, I need help.

Here is the crash report: (I think)
