Why can’t I save or export files on my Mac after adjusting a photo’s file permissions?

I have found a solution to my problem by speaking with Apple support via phone. Here is the solution for anyone who ends up with a similar problem:

Go to Finder and click on folder that you are having problems with (in this case it was the desktop because whenever i tried to drag something (photos, media, word docs, etc.) to it I got various permission errors). Click on three dots and select "Get info". Then unlock the lock. Then change permissions for admin to "read and write". Then lock. This fixed my problem. Thanks to apple phone support!

Dear "Moderator". I wonder if it might be better for you to recharacterized my query title as simply "File permssions problems on mac book pro"? Your changing my title application focus to "Photos" is not getting me enough help. I see that others have had this issue in other catetories. For instance, see this post from 9/2022 until the category "Earlier applications", where the person says: "Every time I download a file, I can't move it or copy it anywhere, I need to do right click -> get info and update all permissions to read/write to be able to do anything with it. If I open an archive it gets worse and I have to update each file's permissions one by one."

In my case, even when I try to reset the permissions on each file, I am still not able to move or save new documents or anything.

Any help or suggestions you may have are appreciated. Thank You.

I would also like to add that it also seems I can no longer delete any item (a word document or a video file or anything) without being prompted now to input my password in the "finder".

yes. that is true. do you or does anyone else have any suggestions for how to fix this. thank you
