constraction changes not stored

[Anonymous]

Dear Community,

I changed a constraction. When I want to save it, the working sign (blue cycle) is visible, but will not finish. When I close/reopen AutodeskFusion, the construction is not actualized.

Yesterday it was working perfect. What could be the reason?

Greetings

can you share the model here?  Can't tell what might be the problem without more information.
