Right click UI and Dropdowns disappearing after click

I am trying to make a game for my uni project, however, I have encountered a bug where the drop-downs and right click UI of any page disappear right after I click on them, sometimes showing for a split second. The UI will randomly work for a random click, then stop working again immediately after. Is there any way to fix this problem? Its been causing me alot of issues.

Same here ! Any help would be appreciated

It seems like quitting discord fixes it !

I have had the same issue. Unreal 5.3, after a Bios update on my Lunovo laptop, having Discord open makes the right-click drop down window immediately disappear..
I have to exit discord in tray in order to do have it work correctly.

Disable overlay in Discord seems to fix it without having to exit Discord entirely.
