Upon starting my unreal engine my drop down menus do not work

[S-ed]

One of my colleagues had similar (not the same) issue. Solution was:

Right-Click Menu / Tool Bar Menu Disappearing?

I also have been running into this issue as well for the past month on both 4.26 and 4.26.1. Whenever the right click issue occurs, I get black screen flashes on chrome as well for some weird reason. The only fix I’ve found for this issue is reverting my Nvidia Game Ready drivers back to the December version.
