Gamecaster- flickering black screen in recording and not responding?

Hi there
I’m new to Xsplit, and tried using Gamecaster to record gameplay on my laptop. I had issues with it when I first downloaded it, so I uninstalled it and downloaded it again. Now whenever I go to stop recording, the program stops responding, and if it does manage to record, the video will keep flicking to a black screen, then back to gameplay. Does anyone know how I could fix this?
Thanks

Hi there, would it be possible for you provide us a saved recording that shows the issue happening?
