None of my tabs are working

Hi,
Whenever I try open the window menu, edit, file, help, etc including the blueprints tab, nothing appears.
I can tell it wants to open a window as the top bar goes white when I click an option but nothing appears.
I have my drivers updated before that question is asked.
Thanks, Darren

I had this issue all the time when I connect second monitor or other display related devices such as HTC Vive, it’s crashing my current UE engines immediately. Try to disconnect second screen or something
