Hi there,

I recently upgraded from 2024.3.821 to 2025.4.1111 and I found some weird issue when deserializing raddiagram xml.  Attached please see two SerializationInfo strings. Both of them can be deserialized in 2024.3.821 but the one named "diagram serialization info_bad" is not able to be deserialized completely in 2025.4.1111. I found the RadDiagramShape with Id = "7cc7b6c3-1606-453d-a9ab-ebc0bd53b207" is causing issue so I removed it from the SerializationInfo Info and named it "diagram serialization info_good". 

Please help me to check why the RadDiagramShape Id = "7cc7b6c3-1606-453d-a9ab-ebc0bd53b207" will cause issue in 2025.43.1111 since it didn't give me any error or exception.

my code is simple as:

SerializationInfo e1 = SerializationInfo.CreateDiagramInfo(serializationInfo);
RadDiagram.Deserialize(e1);

Thank you
