After upgrading Joomla site to 5.46.2 with Mosaico 2.9 and searchkit, there are no recipients available in mail, only showing 'Searching…' in the recipient box.
The problem disappears if debugging is turned on (see comment below from Mark, experiencing same issue in Wordpress).
There is no obviously relevant sign in the logs.
Settings files and urls/directories are clean for 'http://' references and asset caching is off.
Other angular/recipient problems resolved here have identified & resolved 'invisible' recipient groups that still operate. However, in this case, no groups present themselves to be selected.
This ONLY happens with Mosaico enabled. With Mosaico disabled, choosing of recipient groups works fine using 'traditional' interface.
Browser console shows errors:
