Commented Unassigned: Class not found in loaded NetOffice Assemblies [22315]

Applied to Microsoft Access.
I received similar exception when use property Parent for any control if Parent is Form.
You could see one of them in example (button0 on Form1 )

NetOffice.NetOfficeException: Class 49b38fa1-b771-41e1-a8d6-8e65b81fcf97:Form_Form1 not found in loaded NetOffice Assemblies

Comments: Sebastian, System.ComponentModel.TypeDescriptor.GetClassName(ctl.Parent) return Form_Form1. This is evident in the first message. Guid changes with each opening of the Access Application, but the same for different foms: NetOffice.NetOfficeException: Class f47e1d09-6f8c-46c1-8952-c26dfb5d4e5d:Form_Form1 not found in loaded NetOffice Assemblies NetOffice.NetOfficeException: Class f47e1d09-6f8c-46c1-8952-c26dfb5d4e5d:Form_Form2 not found in loaded NetOffice Assemblies Serge
