Problem interacting with widget button in game.
Video showing my problem, it's hard for me to explain it in english.
I have the same problem, in my case it sometimes works sometimes doesn’t. I can’t interact with any widget.
I’m not sure we’ve got the exact same issue but using the ‘Set Input Mode Game and UI’ seems to have fixed the problem for me.
Yep, that’s how it is fixed. Btw it’s a known issue, reported by me in this question. If you wish, you can leave your votes HERE, so the developers would maybe care more about this problem.
