How do I fix random podcast image as album art for music on iPhone after syncing?

Albums without specific album art are showing the same random image on iPhone (but not on my Mac Mini M4 where my library exists.

Some of my music on my Mac Mini has album art and some does not. For the music without any album art I am used to seeing a generic thumbnail image as the album cover, but now all of that music (many artists, albums, etc.) shows the same thumbnail (an actual image) as their album art. Oddly enough, the image that has been adopted is actually the image of a podcast show I listen to. In other words, any music on my iPhone that does not have its own "proper" album art now displays the cover image of the same Podcast show as the album art.

Going into Music on my Mac and manually adding artwork is not a reasonable solution.

This problem has been documented in the community before. Anybody have a solution?
