Could not find widget in the widgets directory

Hello everyone, I have been facing this problem since I upgraded my MX from version 7 to version 9. The funny thing is that when I made some changes the errors appeared and when I synced the app directory  they went away but the widgets still don't work. Since the upgrade and implementation of Atlas_core, I have the theme, theme_atlas2 and theme_old folders, and there are also the themesources, deploymen, etc. folders. I have a feeling that I need to write down the correct widget path somewhere, but I'm not sure if that's the problem and where the exact place is. Please help. Thank you.

You can just import the missing widgets again from the marketplace.
