4.27 right click problem

I normally work in UE5, I’m fairly new. A model I have’s face blendspace doesn’t work in UE5, only UE4. So I decided to just create my short film in UE4. Problem is, sometimes when I’m working I will lose the ability to right click. This is only fixed by restarting UE4. This never happens in UE5. I’m using 4.27, asked in discord and was pointed to a pin that went over a flickering issue. I tried the fix for that, but it didn’t work, so I’m here asking.
