Q: What does a status change from "Editor Assigned" to "Editor Invited" mean?

The status “Editor Assigned” means that your paper was assigned to an Associate Editor (AE) who would be responsible for your manuscript till the first decision. However, the change of status from “Editor Assigned” to “Editor Invited” indicates that the assigned editor has declined the request to handle your paper. Possible reasons for this could be that the editor is too busy with other work or he/s she has a conflict of interest with your paper. The journal has sent out invitation to another editor and once the new editor accepts the request to handle your paper, the status will change back to “Editor Assigned.” This process might take a while, but don't worry, this is quite normal. If the status of your manuscript does not change in another few weeks, you can send a polite inquiry to the journal asking about the status of your manuscript.
