Horizon not Launching Correctly

So recently I downloaded Horizon to get Minecraft maps. It worked at first and everything went smoothly, but then, later that day I decided to do more with Horizon, but it wouldn’t load. I double clicked horizon, the Horizon logo appeared for maybe a second, then disappeared and the app never launched. And, in advance, this is what I have done so far to try to fix it…
Uninstalled then reinstalled Horizon
Installed the most recent .Net Framework
Set Horizon as an Antivirus exception
Disabled my Firewall temporarily
I honestly have no idea what could be causing this. If anyone has any idea how to fix this please help. I thank anyone in advance for helping.

it happen to me as well

same issue here, the logo appears then nothing :-/
