Game Not Opening

I don’t know hat happened, but my game sometimes do not open or it open the forza horizon logo and close and I need to try several times for it to open.
It is not my computer problem because it happens only with Forza,

Did you try to reinstall the game?

You have have the Hang Type Activation error, people discuss it in this thread:

Try using Windows Event Viewer and see if the error being reported after Forza Horizon closes says “Hang Type: Activation.”

My suggestion is don’t waste time/energy reinstalling the whole game, that has not really fixed the issue for anyone. It’s probably a development /coding error on the games part.
