If you urgently need the library, I suggest you downgrade back to the old version for now or do a system restore to a time before the update. Windows 10 should have that option.
Stephen! Thanks for sharing the information. I don’t wanna restore the system because I may lose some other updates for various programs I have. But I like the idea of downgrading. I don’t know how to do it. What should I do to downgrade and do you think that can retrieve my library?
