The library “Photos Library.photoslibrary” could not be recognised.
Hello! I can I fix this? It doesn't work with the command and option keys hold while opening the app.
Thanks!

Hi
Where is the library stored? If on an external drive, what is the format.
Has anything happened to your system prior to this problem starting? EG a system update. If so, what?
Do you use iCloud photos?
Have you used any speed up/clean up apps, or duplicate removal tools?
If you hold down the option key while starting photos, how many libraries are listed. Can you open any of them?
Try restarting in safe mode, and then trying.
