Outstanding. I'll add it to the style and see if it just works.

You can fix this by setting BorderThickness to zero:
The reason the problem arises in 1903 (SDK 18362) is because Microsoft changed the behavior of UWP controls and default values for null when it's a non nullable property type. Traditionally, you'd use "-1", but that is no longer accepted and causes an OutOfRangeException Therefore, by overriding the default -1 value with 0, you avoid the exception.
Note: this also rears it's head in other places, like RadBorder. If you see this exception again, try setting BorderThickness to 0 on those controls as well.

Same here - Windows 1903 also experiencing the same issue.
