what I do: load new snapshot, watch it load and stop at single player option, create new world. watch it load.

what happens: I get a moments view of the new world... sees, grass etc... before i am able to do more than catch my breath though, the whole thing goes blank and I get a crash notice, usually with no report listed. just a "sorry for the inconvenience." note. and I am at the launch once more. with a windows wings stating javaw has crashed floating beside the launch window.

(but for once.. which i have added this file to attachments.)

re-creatable?  ohyeah. this has been the case for me since snapshot 18w44a

Do other versions work? yes. 1.13.2 works fine. strangely, snapshot 18w43c seems to work fine as well... just nothing after this.

tried to fix?  JVM argument changes have no effect. crash in just created world continues. Tried loading a new launcher and it causes the whole game to crash and refuse to work.
