Unable to enable iCloud for Photos

I was pruning my hard drive on my mac and found a local file in my Home/Pictures directory with a .photoslibrary extension that contained what seemed like an exact duplicate of the photos I stored in iCloud, but in my local disk. I proceeded to manually delete that 15gb file => move to trash => empty trash, which cleared the space, but also corrupted my Photos app. At first, before deleting the .photoslibrary file, I tried to disable iCloud for Photos, which prompts you to delete local photos, which will remain in the cloud in full, but it only managed to delete an insignificant amount of low resolution backups. Now, after removing the .photoslibrary file, which seemed to be the core system file created by the OS, I'm unable to re-enable iCloud for Photos, which I thought I could do to then access the photos I can verify still exist on the cloud, on my mac. To note, the Photos app still works, but it opens blank, and I had to create a new photo library to get it to open properly, since I mentioned the previous .photoslibrary file I deleted was the default/core file the system was using. Is there any way to solve this problem? Just want to be able to access photos stored on iCloud on my mac again with the Photos app. Thanks!!
