Since last two days I am facing issue regarding the maximum brightness in my pc, yesterday it got solved somehow, but I don't know how, again when I set my pc to restart, it came back with this bug again

It once happened that many programs were running simultaneously in my pc but all these programs were running normally,
- Youtube Video
- Ubuntu Software
- Brave & Firefox and
- VS Code

And at some point when the battery turned out to be low, I charged it again but there seems to be an overlay .. Something like a dimmer sheet on the main screen, (I can say this coz my mouse pointer is visible at accurate brightness, the brightness at which I see my BIOS screen)

This all happened on Friday, which turned out to be normal after several restarts and some codes which I don't remember, Now this happened again Today(Sunday) and is not getting back to normal after several attempts..

Thank you very much for reading this.
