Deserialize a dictionnary and removing one element

I saved a dictionnary using the Serialization package. It worked well.

Unfortunatelly one of the element was bad defined (a function with elements not recognize… which I do not understand why since I thought it was compiled but anyway).

So, I have a simple question: would it be possible to partially deserialized the elements of the dictionnary (removing the one which is not working)? The idea behind is that it come from simulation I run for a day on a huge machine (costy), so I’d be happy to not restart everything.

Thank you.
