MC has strange look and crashes when opening a map

Probably the changes of the rendering engine could be the problem. There is no problem with sound (If it is necessary to know)

1st- When MC starts the letters look like white squares and there is no background (in older versions of MC did not do that). (Image)

2nd- Opening a map (all game modes) will crash MC without crash report; just closes the window and there is not bug report file.
