no crash report

launcher log + game output from the mc launcher after your game fails then.

and the launcher does not reappear after it disappears

on launcher, hit edit profile and select keep launcher open. Hit save profile and try again.

i also looked at the game output and it said unable to launch and it also did not launch

and this is what it fully said
