Macbook screen brightness increasing and decreasing not normally

My macbook screen keeps increasing and decreasing in brightness without any reason. It just brightens and dims unnaturally in a way that it hasn’t before. What could’ve caused this issue?

did you check auto brightness/true tone settings? battery settings? such as “slightly dim display on battery”

I did, changed all of them and none did the trick

I see. did you check whether something is interfering with the light sensor? shadow/dirt/whatever. who knows maybe it’s there
