update icon with exclamation point

[Staedtlerp]

Good morning to all:smile:
I have a problem with updating a product, or better my product does not update and the update icon is always active with the yellow exclamation point. I attach the photo for clarity. for convenience I placed the design mode icon next to that of the upgrade :biggrin:
Does anyone know what it means and how to solve it?
Thank you very much:

usually happens when you have a component loaded in display mode, which you can't load ( missing component? component with solid not updated inside? etc.) try with rescue management to check if a component is not present.

thank you for the answer:smile: it is for this reason that I positioned the design mode command next to the upgrade. in fact the first thing I did is press the design mode command but nothing changed. I also tried, as you suggested, to check everything in rescue management but nothing....all parts and assemblies are "open" I don't know what to do...it's very strange that I can't update. even when I press the button to update nothing happens, the update window opens but closes immediately, as if it had nothing to update any other suggestions?? ? Thank you very much:

ok found error :biggrin: I found a part that inside it contained nothing even if it was correctly displayed, it is seen that when I saved it something went wrong :biggrin: you were right gianni55, a part had loaded without loading anything inside it, it was like an empty container even if it displayed everything correctly and did not indicate anything abnormal in the rescue management window. I don't know why he didn't load anything

Thank you so much gianni55:finger:
