Hi,

Trying to solve the above errors.

- I’ve removed Panel2 but SLS still generates an error when opening the project.
- The ‘RotateButton’ Widget is not in my project either

How do I solve these errors?

Hi,

In the error panel, the purple elements are the components. You deleted the Panel2 from the screen, but the component still exists and still has these errors. Either delete the Panle2 component from the Widget panel, or correct the image reference error in the component.
