     Testing Tests interrupted. Exiting the test process

In #67 I found the line that seems to be triggering the issue (which is simply calling show on a video player widget -- it makes no sense to me) and disabled it for Windows.

The change I made yesterday had nothing to do with the player widget, so I would guess this is related to a recent upgrade of GTK4_jll that will either have to be worked around or will be solved by another upgrade.
