UI Widgets unresponsive in standalone

Development Programming & Scripting UI

Hi, few days ago I started working on a Multiplayer system from this tutorial - Blueprint Multiplayer
Everything worked fine, but when steam was implemented and I had to start the game in Standalone Mode, the UI wasn’t getting input, or was frozen, completely unresponsive. In Viewport it works, except when i click on empty part of a window where there is no box or button, then it becomes unresponsive too.

I have no idea what might be causing this. I’ve searched the forums and the answerhub but it seems I’m the only one with this problem.
If you know something about this, please let me know.

Thank you.

I had the same problem. I solved it by adding a “Set Input Mode Game and UI” call after the call to “Add to Viewport” in the “ShowMainMenu” custom event in the game instance blueprint.

Unfortunately, I now having the same problem with the lobby menu. I added a call to “Set Input Mode Game and UI” but it still won’t accept clicks. My character moves around though in the lobby.
