I’m a beginner and I can’t discover what is my mistake.
When run Open Level module always does message log “CreateWidget called with a null class.”
Please someone knows a solution?

Try open level by name. Just to remove that from the equation?

Not understand your question, sorry but my English isn’t very well…

Does this level add a widget to the screen? Have you specified the type of widget?

5

No, this level I try to open hasn’t a widget, for this reason I don’t understand. I tried to open other levels even new levels just creates and always I have the same result.

6

Have you been editing the game mode, or player controller?

7

Yes, I created a new game mode class with new default pawn class.

Wherever you have specified your game mode, project settings or world settings, I wonder if the HUD you’ve specified there has a problem. Try just clearing that

I’ve tested with different options of GameMode with the same result.
Then I’ve created a new MenuLevel, BP Interface menu and even a new level to call it by button into new interface and again the same error.
But at that moment I’ve thought … I have a different plugins installed for testing and probably something still be enabled … that was it!!!
I had the CommonLoadingScreen plugin enabled and when I’ve disabled it all it works again!!!

Thanks a lot for your knowledge and help.
