So, after a fine time with rad 2, suddenly, it decides it no longer wishes to start. So after looking it up, I found out that Java 15 was supposedly my only option.
So, I uninstall java by deleting the folder in the C/program files/ java folder.
So, I reinstall java. It doesn't work. Fine, I reinstall Java 8, 19.
And now, java just flat-out doesn't like me. Minecraft servers don't start (They crash immediately.)
and using the "launch.bat" yields these results.
