Insertion failed error

good morning everyone,
in Catia on the 3Dexperience platform in the cloud a strange thing happens, as soon as I insert a 2D drawing into the Physical product the save fails inserting the error:

insertion failed = false

if I delete the 2d instead it saves normally.

Have any of you been in the same situation?
Can you help me to solve the problem?
The machine is a Lenovo notebook workstation certified with cloud eligibility parameters all ok.

Thanks

 

 

Cosimo
