Player boot time

Hello,
On some of my clients, it takes few minutes (1 or 2 min) to start xibo, sometimes a black or white screen replaces the splash screen.
afterwards, the different regions of the screen start to appear one after the other
while on other players with the same version it starts directly
Another question: can updating Windows affect the operation of the player?
NB: I am using version 2.252.5
Thank you
