Windows 10: Random screen dimming and loss of brightness control

Windows 10 build 20H2
Dell Inspiron 7570

If I increase the brightness of the display using the brightness keys to reach maximum brightness, and then decrease brightness to minimum; Now if I increase the brightness once again to the maximum, it results in significantly lowered peak brightness. Repeating this process one more time results in complete loss of brightness control

The problem stops after a restart, however sometime while running, the screen dims and the problem starts again. In fact the screen dims during use and not inactivity which is strange. This problem persists even though the laptop is plugged-in
I have installed latest display drivers and updated windows as well, but it did not stop the problem. I have tried disabling and then enabling the display driver from Device Manager, but again no change.

Screen dimming even at 100% brightness

Hi recently bought a Lenovo laptop, a Lenovo V14-ARE laptop, and as soon as I turned it on I noticed, when I put it on 100% brightness it is bright and vivid but then it dims. After a while, the screen brightens again then proceeds to dim once again in a
few seconds. When I plug it in to charge, the screen is bright and vivid but as soon as I unplug it, it dims. I already left clicked on the power icon in the task bar, went to power options and selected "choose when to turn off the display", clicked "change
advanced power settings", scrolled down to "display" and opened its list, but the only option I have for the display's list is "turn off display after", in the Youtube videos I've seen they have an "adaptive brightness" setting or something like that and that
fixes their problem but I don't have that option. My power plan is also in high performance and everything is "on battery" but the problem still happens.

Can this problem be fixed?
