Message is "Photos cannot load edits for this image". Also, many photos will not complete the export command with an error message stating "unknown error -1 cannot create file".....
Not sure if it's icloud related, but think not, as it impacts photos on the hard drive of my mac studio??

It sounds like you are using iCloud to sync your mac and iPhone. Do you have "Optimize Storage" checked for Photos on your Studio? Is your Photos Library listed as your System Library-- in Settings>General or by quitting Photos and option-clicking on the Photos icon.
In Settings>General, do you have "Copy items" checked?
Here, "Use as System Library" is grayed out because it already is.
What happens exactly, rather than "cannot edit" etc? When you choose Edit, what happens? Does Photos quit? Does the picture pop up and won't edit? What do you see?
The things you list would be happen if you don't have the full sized images on your local drive, but rely on iCloud to help reduce the local storage load. Then Photos would try to download the full image so you could edit or print or export it. If iCloud isn't available, which it wouldn't be if this were not your System Library, then it wouldn't work.
Another possibility is that you don't have "Copy Items" checked and Photos has lost touch with your referenced files.
Let us know so we can go further...
Appreciate all the replies - thank you!
Been away, hence delay in responding.
"Box for using system photo library is greyed out"
This means that the library is already the system photos library.
The cloud icon in the corner of the image is indicating that Photos cannot access the originals in iCloud.
There are several possible reasons for this.
Also, you may want to check, if the photos in question are still in iCloud. You can check this, if you view your iCloud Photos Library in a web browser on your iCloud webpage at www.icloud.com and open the Photos.app on that web page.
Library stored on local HD not external, though Time Machine backs up to one. Have tried changing permissions, no change. Tested taking a pic and airdropped it in....works fine with no restrictions. Have used Macs since the early days, so multiple migrations etc.....
If the photos have been migrated from an Aperture or iPhoto Library, and they have been edited in Aperture or Photo, you cannot edit them further in Photos, unless you revert the photo to the original.
The edits applied in Aperture or iPhoto will have been migrated as previews of the edited versions, as Photos cannot replicate the adjustments applied in the other apps. The previews may not be of a sufficient quality or not available at all, if we did not set Aperture to render high-quality previews before the migration to Photos. We have to discard the previous edits, if we want to edit these Photos in Photos. Try, if you can edit one of the problematic photos when you use the command "Image > revert to original" before you try to edit the photo.
Updated - Actually, cannot upload,edit or export about 50% of my 6000+ photo library...
On what device? Mac? iPad? iPhone? What version of the OS?
Apologies- On 32gig Mac Studio using Mac OS 14.4.1.....
Where is the library stored? If on an external what format is that?
Error occurs when trying to Edit or Export photos
