Cannot make app copy

I try to make save project as but it showed me this message
" server error could not copy project"

Check if the site is running fine by visiting Kodular Status: https://status.kodular.io/.

If the problem still persists, hard-refresh the site by the shortcut Ctrl + Shift + R. Then, open your project and try again. If you are using the free plan, make sure you have less than 10 projects in order to make a copy.

I did all steps you recommend but still showed same error
