Minecraft Java Edition Error "Launching the game failed"

I used to play minecraft often but suddenly I began to stop a few years earlier since most of the time my launcher failed to launch. Now I'm coming back to minecraft to play again but there seems to be a new bug for me which I cannot fix

I tried to reinstall everything but didn't work

I tried restarting my computer and didn't work either

 I followed the mere instructions but didn;t know what to do

Can you please help ? Thank you
