Keyboard stops responding in Source Monitor
Since updating to 14.5.0 the keyboard has been unresponsive while in the source monitor. Resetting/deleting preferences didn't help.
The issue seems to resolve if I open Premiere through the project file in Windows explorer. If I open Premiere first and try to load the project (or use the quick start menu), the keyboard does not respond in the source monitor.

I am also experiencing this and can replicated the "fix" the same way. It affects my source monitor and program monitor which are both on my second physical monitor.
