I managed to solve my mistake in the launcher, I just changed the computer date to the exact date of today and at the same time, just that my launcher tried to open in the future and did not update.
for me the same problem , the only way i can close the minecraft "blank window "is from the task manager ,(the logs don't show anything. the RAM memory stay as the same level as the game before it freezes at the loading screen and it does'nt fluctuate
