MBA (M1) power button and screen flickering when waking after sleep

So in my M1 model I have this strange behaviour, after a few minutes of sleep when I have to wake the MBA I have to press/click the power/ID button and the screen turns on and off right away, if its sleeping for a short period of time it works just fine.

After this first on off screen if I need a second touch to turn the screen and go to login screen (or directly to desktop if touch ID is enable), if I wait without login, and let it go back to sleep I can use the power button just fine no screen flickering, if i wait for a few more minutes the screen flickering happens again.

Also with touch ID enable when I login sometimes the window with the option turn off, restart, sleep just pop-up, I don't even know how to make this happen using the power button if I want.

If I press the button very fast the issue most times doesn't happen.

I'm a bit confused with this, looks like some kind of bug, I found some other users in macrumors and reedit with this issue, or is some hardware issue, some double click when clicking once, but why in short sleep doesn't happen and when a I'm in the desktop if I touch it goes to user login, if I double click it actually doesn't do nothing (like turning on off screen).

Some update:

Maybe is something related with security and privacy, I think I change the time for password before this start happening, so if I set it to 8h, and after a log sleep, if I press power button no screen flickering, but a turn on in log in screen, them a black screen with mouse cursor and back to log in screen, and I have to use touch ID or password, and I didn't wait 8h only a few minutes.

For short sleep period pressing the power button goes directly to desktop.
