musescore files created after 1-1-2023 not loading in musescore 4 app on iPad

I successfully imported musescore files to my iPad until around Jan. 1, 2023. Now, instead of getting the name of the file, I get a nine-digit number. No parts appear for the file in the offline songbook. However, I am still able to successfully import scores that I created before 1-1-2023. This is VERY frustrating.
I've attached a file that I created today and have been unsuccessful at importing to the iPad app.
