Effective with Lightroom Classic 11 (because of the new masking) it is necessary to send the .lrcat and the .lrcat-data (if it exists) along with the Smart Previews. yourcatalogname.lrcat-data contains any AI-generated masks (in pixel form) that belong to the images in that catalog. Can you send the .lrcat-data to the client and have them place it alongside their .lrcat file (with Lightroom Classic closed) and relaunch Lightroom and see if the masks will reconnect?
Now, having said that, it should not be necessary to recompute the AI mask but there may be a quality advantage to recomputing it when you are attached to the original over the smart preview.
Note: This also applies to other shared catalog scenarios such as sharing a catalog within other users or desktop to laptop.
