Brightness goes down to black screen on itself!

I successfully installed macOS ventura with almost everything working on my HP elitebook x360 1030 G3

However, for some odd reason, if I tried to use the screen in an angle more than 180 degrees, the screen shows as if you are lowering the brightness until the screen goes totally off.

Then you can get the screen back even if you tried to change the brightness using the keys. The laptop is still on and you can hear it if you clicked on any button but black screen after going beyond 180 degrees until you force restart.
