When I do a clone slide on a slide with a bullet, I get the following error:

System.ArgumentException: '-7.26' is not a valid value for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue.

I upgraded to 2.4.5.0 and now I receive the following exception:

Message: "Object reference not set to an instance of an object."

Is there any update on this?

destinationPresentation variable is not initialized in your example

Please see attached example.

destinationPresentation is null (Nothing) when you call CloneSlide method.
How slide should be cloned in this case?

Sorry about that! Thank you for your help. Rolling back in versions (and fixing my test), the problem is fixed in 2.4.4.0 (and now 2.4.5.0).

Thanks again.
