On Tahoe and earlier, ScreenCapture permissions can disappear and not return. Customers are having an issue with this disappearing and when our code executes CGRequestScreenCaptureAccess() nothing happens, the prompt does not appear. I can reproduce this by using the "-" button and removing the entry in the settings, then adding it back with the "+" button. CGPreflightScreenCaptureAccess() always returns the correct value but once the entry has been removed, CGRequestScreenCaptureAccess() requires a reboot before it will work again.
