Widgets aren't showing up in packaged game

Have you tried something else from “Add to Player Screen”? I mostly use ‘Add to Viewport’ BUT I am working with UE4, not 5 so there may be different names or it may be gone from this version

Also, are ALL of your Widgets affected?

You can also try making a HUD Class that will contain all of those Widgets and Functions to open/close them

You can easily get access to your HUD by using “Get HUD” and then Cast to YourCustomHUD to get the Functions you have there

Also you can try adding some PrintString nodes to see if it even triggers in the game at all

NOTE: PrintString doesn’t work if you package for Shipping, Development Package allows using them as well the Console on tilde button

Sometimes all you have to do is to remove the piece of code and recreate (not copy and paste back), this helped me once when in a packaged VR game my BPI for grabbing wasn’t working

Another tip - create a new Project that’s totally blank, migrate your actual Project there and test

Just make sure you set your Defaults back to what it should be (especially Maps and Modes and the Inputs)
