MaterialDesignSwitchToggleButton: 'System.Windows.Media.Animation.DoubleAnimation' cannot use default origin value of 'NaN' on Window Exit #3740
Description
Bug explanation
Moving to Material Design 3. Having a problem with MaterialDesignSwitchToggleButton. The other ToggleButtons styles don't appear to have this exception.
When closing the parent window after this style has been loaded, I get an exception. I am guessing the exit animation is causing this. Not sure if it's because there is no from value?
I am still researching this and have not created a side project to test this yet. That will be next, but under pressure to finish this project, so will select a different style for the meantime.
Exception is crazy long, so will post the final part of it.
System.InvalidOperationException: 'System.Windows.Media.Animation.DoubleAnimation' cannot use default origin value of 'NaN'.

More to come - but opening this up just in case there is something obvious I may be missing.
