everytime i try to put a game into fullscreen or change my monitor refresh rate back up to 144 hz it glitches and turns the screen black

After putting my game into fullscreen or trying to set my refresh rate back to 144 hz it makes my screen glitch and my whole screen goes black or stutters horribly.

Can't change screen refresh rate to 144 Hz

So i just got a new monitor (msi optix ag32c) and windows 10 doesn't let me change the refresh rate of the screen over 60 hertz?!

I asked from msi that why i cant change it to 144 hz and they said that i need to shut down my computer and remove the power cord and hdmi cable and wait 1 min and i tried that like 5 times but it didnt work. The monitor also doesnt have any drivers for
user download so windows 10 says that its a "generic pnp display".

So please dont comment " just right click on desktop and click advanced display settings."

Note: I am using HDMI and not DisplayPort and msi said that HDMI can only support 144 hz with this monitor.
