AV16-51P-Brightness stops working at random,unable to change (increase/decrease)the brightness level

Unable to change (increase/decrease) the brightness level on my Acer AV16-51P laptop. I have tried through keyboard keys, system tray as well as system settings. There are no power settings that might be affecting this, I was able to change until about 5mins back. The only thing I could notice was while switching between multiple apps (youtube, spotify, onenote), system froze for about 3seconds and then the brightness level has been stuck ever since.

A quick reboot of the system fixes this issue, but I don't want to keep rebooting my system every time this issue happens.

Which Cpu it has? AMD OR INTEL?

Intel(R) Core(TM) Ultra 7 155U 1.70 GHz

I have disabled Hardware Acceleration on both Chrome and Spotify apps separately, hoping this should fix the issue. I'll monitor for the next few days.

Consider disabling adaptive brightness in the power settings:

Open Control Panel > Power Options.
Select your active power plan and click Change plan settings.
Click Change advanced power settings, expand Display, and set Enable adaptive brightness to Off

Also, Intel Display Power-Saving Technology: This feature adjusts brightness based on content, which may lead to unwanted fluctuations. Disabling it in the Intel Graphics Command Center can help
