Hi @Sjdalts, welcome to the forum 
Where are you looking for the videos? I expect they’re likely recording to Documents/QGroundControl Daily/Videos, in which case they won’t appear if you’re checking in Documents/QGroundControl/Videos.
I would also recommend trying the different video decoding options in the Application Settings, in case one of them works better than the default.
Note also that our latest recommended version at the moment is still 4.1.7, so it may be worth trying that instead to see if it works better.
If none of that is helpful, are you running Companion? BlueOS will hopefully work better.
