Video playback skips to the end
Quite frequently I find that when I try to play a video on my new 16" MacBook Pro (macOS Catalina 10.15.4) it immediately skips to the end. When this starts happening it happens everywhere - Finder preview, in Quicktime Player, on YouTube, on other web sites - everywhere! The only solution is to restart which fixes the problem for a while but then it happens again. I am sick of having to restart my Mac just to be able to play a movie. However, I haven't been able to find anyone else having the same problem so it might be caused by something I have installed.
Any ideas?
I have published to YouTube this screen recording showing the problem happening.
