Frankly the amount of variables involved and the apparently random nature of this issue make the odds of false positives for "solutions" super high.
Since it happened to me for the first time (more than one year ago) it sometimes kept happening for some days in a row, then it stopped for a couple of months until it happens again with some weird and unexpected frequency. And meanwhile we try so many things to figure it out that when it stops for a longer period it's easy to attribute a wrong solution and share it here on the forums until it happens again couple of months later.
Since the beginning I went through several Windows updates, went back to Win10 then back to 11 again, many Nvidia drivers, removed and installed many software etc... Eventually the issue always get back to haunt me.
Given I also suffers (way more frequently) with the black checkerboard artifacts on chrome/edge which is a very well known issue with Windows/Nvidia compatibility (still not fixed), I strongly believe the blinking screen is just one more of those buried bugs that are not common enough for the developers to care about it.
