4.18 Visual Studio Error/Freeze With Video

Hello krisgoku2,

Thank you for reporting this issue. I actually saw this occurring yesterday when testing another issue and entered a bug report for it. You can find the bug report here: UE-51608

For the moment, the only workaround would be to wait. It does eventually fix itself, but it takes a while. Please follow the progress of the bug at the link provided.

Have a nice day!
