Unable to adjust screen brightness

I am unable to adjust my screen brightness on Zorin OS 16. I installed zorin on my Acer Aspire 314 with an AMD Ryzen 7250U processor. I checked all the solutions on the forum and none of them seem to be working. Also it seems that this problem comes in all Acer Aspire series laptops. I tried many solutions suggested on the forum like changing the grub configuration and using a third party brightness controller but none of it seems to be working. Using the buttons and slider both show that the brightness has changed but my eyes tell me otherwise.
