Reinstall Epic games


I would like reinstall EPIC GAMES Launcher for playing to Fortnite. But systematicelly, on my macbookpro, we are able to launch the installation, after dowloading the latest version, but at the end we have a black window indicating us that it is crashed.

I desintalled all the game completely since 1 month, and we cannot use it again.
My son , and I, doesn’t know how to namge this matter.

Thanks for your support,
