Project Browser window not opening after hitting Launch Button on any version of Unreal Engine

Need help, project browser window is not showing up. I keep hitting the yellow launch button on different versions of Unreal Engine, but nothing happens. When I click on the Launch button it says please wait then reverts back to the Launch icon and no window shows up to open a project or start a new one. Need help, I have tried writing -http=wininet or -OpenGL and it does not work. Really don’t know what to do.

  • Look for errors in Engine/Logs/UE4.log. If there are any, and you are not able to solve it yourself, post here.
  • Try verifying engine (The down arrow near “Launch” button in Library section → Verify)


Getting the same issue, it just auto opens my last project in UE5
