Hi there,
Sorry, but unfortunately those cloud icons can be misleading.
Creative Cloud file syncing for Premiere Rush was discontinued, and projects and media that existed only in the cloud needed to be downloaded or backed up before that service was removed.
If the project media is no longer available locally on one of your devices and there is no separate backup, unfortunately there isn't a way to retrieve the deleted cloud copies now.
You can find more information here:

I'm very sorry I don't have better news.
Thanks,
Kevin
