Can't get games to work in SC2 or HoTS

I can’t get games to start in SC2 or HoTS, the game buttons are grayed out. All the other blizzard games seem to work fine (WoW, reforged, D2)

I have allowed both games in Windows Defender.
I also flushed the DNS.
I uninstalled and reinstalled SC2.
I reset the game settings.
I reset my router.

It works on other computers on my routers network just not mine.

Did you try to scan and repair? Usually a gray button means the game cannot be located.
