The title of the issue mostly describes it, but whenever I load 18w19a or 18w19b on startup it just crashes. I have also tried the latest java version and that was no help. I have also tried creating another save directory (since I have a lot of worlds and since loading old worlds was removed I was thinking that was the problem) but that didn't work as well. It also doesn't give me a crash report (as usual) so I will just give a log because that has the problem.
