I am using ArcGIS Pro 3.0.3 to publish/overwrite an annotation Map Service on our stand-alone ArcGIS Server running 10.9.1 with all the current patches. This morning I created a new annotation layer, added it to the map I publish from, and attempted to overwrite the existing Map Service to the ArcGIS Server. At the end of the publishing process, I received an error message that the overwrite failed to publish the map service. Upon looking at the log, the following error message was found: "StatusMessage: ERROR 001487: Failed to update the published service with the server-side data location. Please see the server's log for more details."
The server logs indicated the new Annotation failed to update the connection string for the new annotation layer.

The new annotation layer uses the exact connection string as the other annotation layers and is contained in the same Enterprise database dataset as the other annotation layers. If I remove the new annotation layer, the map will publish to the ArcGIS Server without issue. I created a new ArcGIS Pro project and added all the annotation layers into a new map from the same data connection with the same results. The map will only publish without the new layer included. It does not make sense that this is a connection string issue when all the data is from the same source. There should be an issue with the older data as well.
One difference I did note, the other annotation layers are from ArcGIS Pro version 2.x and have not been updated. In comparison, the new annotation layer is from the 3.x release.

Any idea why this annotation layer will not publish?
