Electronics - Error when locking copper layers with polygons

[20367BUL8S]

When you add a copper pour to a copper layer and then lock that layer, it gives the polygon pour the 'lock' attribute and fusion throws an error.

@20367BUL8S , use one of the following solutions:

• Continue normal work by clicking the OK button when notification will show up while opening a project in Fusion 360.
• Go to the Layer tool and unlock every copper layer then save the PCB design.
