github.com/NickeManarin/ScreenToGif@55b6ad12bd/ScreenToGif/App.xaml.cs (L81)

So it looks like you check user for null but not AccountDomainSid. AccountDomainSid can actually be null as well which causes an exception when you run the app.

Fix is to change to user.Value.ToString()

var mutexName = (user != null ? user.Value.ToString() : Environment.UserName) + "_" + location;

Ok, I'm going to replace with:

var mutexName = (user?.Value ?? Environment.UserName) + "_" + location;

Thanks.
