My iTunes 12.9.4 keeps freezing

Same challenge.

I am on a Win 11 desktop. I have spent a lot of time narrowing down what drives the freeze. This is what I have sound so far. As a note, I had both the Microsoft team and Apple Support teams screen share and watch what was happening and what caused iTunes to freeze. As usual, they both blame each other.

My iTunes 12.12.9.4 app freezes when:

• I add a song to my iTunes library from the apple catalog. As a note, the song will play if played on the Apple platform but will freeze when moved into your library. The song may play once you move it into your library but the iTunes app freezes after that requiring the user to force the app closed through Task Master.
• If I replace a song in my library with a new file from the apple platform

I can play all songs on the apple platform with no issues. I can play all my songs in my iTunes library once the app is restarted and I don't add any new songs.

The bottom line: The iTunes app freezes if you add a new song to your library from their platform.

I also have no problems with adding songs through Apple Music from my iPhone or iPad. This appears to be an issue limited to iTunes 12.12.9.4

All other apps and software on my Win 11 machine run as normal even after the iTunes app is frozen.

I have uninstalled, cleared all apple entries and have the same result. When trying to downgrade, the upgrade will not proceed due to the library. itl file requiring the most current version (12.12.9.4) to access and finish installing. We are stuck using other apple devices to add music until they debug and update this more current release with iTunes.
