Honestly, the launchers don't really change anything. It's the exact same error

same result, doesn't change anything

yes i did. sztill the same problem. Oh and i already did the java method and that also didn't work.

I'm about ready to give up and buy a new laptop

i did that too that path doesn't exist

Remove Java at C:/ProgramData/Oracle/Java/javapath/javaw.exe

Reinstall Java 8

https://www.java.com/en/download/

The new Java Path should be

C:\Program Files\Java\jre1.8.0_231\javaw.exe

Set this path in your Launcher and test it again

i was late in pposting this, but i removed protonvpn and this was what i got:
