(UE5) EA 2 Event On Mouse Enter not working. UE5

Been following a tutorial for a more advanced inventory This one. But at about 3:55 a simple “Event On Mouse Enter” will not work in UE5EA2. No problem in UE4.

But this is also effecting the Drag and drop.

Someone having the same problem?

Hi,
Did you ever find out what was causing this?
I have the same issue. It’s crazy because I have another project with the exact same settings which is working just fine. I don’t get it, it’s so frustrating!
