Photos can't find library - macos monterey 12.1 photos error PHPhotosErrorDomain error -1

Renaming definitely wasn't the fix. I'm new to Mac. The last time I used Apple was in the early '80s when I was the company programmer on their Apple 2. Clicking on "/iCloud/Photos/Photos Library 2/photoslibrary" seems to have resolved the issue. At least it found a library it was happy with. It won't allow me to create nor access a previously set up library that's on the drive or on Microsoft OneDrive. I get the aforementioned error: "The operation couldn’t be completed. (PHPhotosErrorDomain error -1.)."

I consider the matter resolved. Thanks!!!

I think it's working. Specifically, based on a comment by the original poster in this thread: Photos unable to open library after Catal… - Apple Community, I opened Finder and clicked on "iCloud Drive/Photos/Photos Library 2.photoslibrary". Photos immediately opened. It allowed me to import photos from somewhere (I thought it was from my iPhone, but apparently it wasn't). I noticed that all the photos from the last 3 years were missing, so I clicked on Glen's iPhone in Finder and was told that I needed to unlock my iPhone. After doing so, Photos is now importing all my photos and videos from my iPhone. This apparently is going to take awhile. I work nights and sleep days. I'm not going to sit up to see if it works. I'll check again tonight and post to the list if Photos is working. At this point I'm going to say that it is.

It didn't work. The first time I tried, I received an error stating that the library couldn't be repaired. So I created a new one. Now I'm getting this:
