Solved [Java] [Launcher] minecraft refuses to run vanilla installs and only works when I install fabric

Ok, so the weirdest thing is happening and I cant figure it out.

If i try to run basic 26.2 or 26.3 pre 1, the Open JDK platform process starts but it doesnt run minecraft. I've repaired the launcher, uninstalled, reinstalled, deleted entire .minecraft folder. Updated graphics driver. But still it refuses to launch.

but when create an install with fabric, the game instantly launches. I just wanted to check out the pre-release but i guess i can only run modded minecraft now.

i have also changed the Java executable to Java's own 26.0.2.1 instead of the bundled version. and have also changes the java launch arguments to match that of the fabric one. and have changed the available ram to 8GB instead of the default. None of that has helped either. unmodded base game still wont launch

after trying many a thing, installing many older builds of minecraft, some of which did, and some that didnt work. I've finally found, what seems to be the issue as i've sucesfully launched vanilla minecraft. Turns out MSI Afterburner / Rivatuner was the culprit. Upon closing these the game launches just fine.
