IT IS NOT 1.19.3 THERE WAS NOT AN OPTION FOR THIS VERSION.

when I go into the new launcher and old launcher and try to open 3D shareware, the April fools snapshot the game opens for a second then it crashes getting the exit code -805306369 and the log says 

1. 1. 1. 1. 1. 1. 1. 1. 1. 1. GL ERROR ##########

                              this is also new because yesterday this worked just fine.
