Starting GTA San Andreas reverts Refresh Rate to 60 hz

Hello everyone!

When I start GTA San Andreas my monitor reverts to 60 hz. Before starting the game it's 144 hz and after quitting the game it's 144 hz again. To fix this in the game I must minimize the game and then change it in the control panel, but how can I fix it permanently?
I want to force the game to run in 144 hz. It should be possible because I didn't have this problem prior to reinstallation.

 

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.

 

Can't set my DisplayPort monitor to 144 Hz in Windows 10 October 2018 Update

That is not the main problem. Lowering my refresh rate is a temporary solution, as my monitor supports 144 Hz. I have been using the 144 Hz with no trouble until this October 2018 Update, where I can't set my monitor to that refresh rate on the Windows
or NVIDIA config, or it will go black despite still being recognized by the OS.
