Hello Steven K3,
Thank you for using Microsoft products and posting to the community.
We fully understand the inconvenience the issue has caused and that the current situation can be frustrating. However, I have to say that there is much user feedback in Apple forums and also in Microsoft Store about the poor performance of this application.
When starting or closing iTunes in Win11,… - Apple Community
iTunes Windows 11 opens then freezes with… - Apple Community
iTunes - Microsoft Apps ****
In my further search, I noticed that the application has not been updated for a long time. Here is the download information from Apple's website, from which you can see that the iTunes for Windows application has not been updated for a long time.

But Windows is in a constant state of updating, and if the application is not actively updated for Windows, then there will be some problems in using it. Although Apple says that everything is fine, the above feedback from users suggests that the app has had problems for a long time. The best thing that can be done is for Apple to continue updating the application to be compatible with Windows, so that similar situations could be avoided.
Also, in case you don't have problems using this app on a Mac, it's actually because iTunes for Windows is not the same app as iTunes for Mac. Although they have the same name, their design kernels are different due to the different platforms they are used on. iTunes application is developed by Apple, so it is normal for this application to be adapted to its Mac system. But for iTunes application to be compatible with Windows, it needs to be constantly updated for compatibility. Sometimes Windows updates make changes, and if the application doesn't respond in a timely manner, I'm afraid compatibility issues are very possible.
Hope you are keeping safe and well. Please feel free to post back if you need further assistance.
Sincerely
