.mscz files created after Jan. 1, 2023 (approx.) can not be successfully imported into musescore 4 app on iPad

I am unable to successfully import a .mscz file created after Jan. 1, 2023 (or thereabouts) to the musescore 4 app on iPad. The file imports but when it opens, the screen is blank. And, the file name is just a nine-digit number. Although, I can successfully import .mscz files that were created BEFORE Jan. 1, 2023. This is very frustrating. I've attached a file that I created today and can not import into musescore 4 app.
If this is not the proper place to log an app-related issue, please let me know where I can post.
Thanks.
