It doesn't generate a crash report, even when holding f3 + c for 10 seconds like instructed to in other bug reports. I'm not sure what I'm expected to do when it just freezes. All I'm getting is the menu screen telling me an unexpected error occured. I'm running 1.12.2 with optifine with absolutely no trouble, I'm allocating 5 gigs worth of memory to the game so that can't be it either. What else can I do to force a crash report out?
I'm having the exact same issue, but it's affecting all my versions, not just snapshots. This goes back a good bit even, I tried running 1.8 and it gave me the same exact pseudo crash.
