‘Photoshop could not save as "yourfilename.psd" because of a program error.’
Still not working Photoshop 22.1.1 MacOS (10.15.7 and BIG SUR).
When working local (MacOS) no problem saving - edit - save.
When I work remote (MacOS to Windows NAS Server) get the error.
1- Start with making a fresh new document/file
2- Save it to remote server (works fine)
3- Edit some content in file then Save
4- Get error when saving file
5 - PS makes a "Adobe Photoshop 2021162925289454108" type of files on the sever. And does not delete them.
A- copy the file from the remote server to my desktop
B- open the Photoshop file on my onlocal (Mac) computer
C- Edit / save / edit / save- no problem
D- So the file is okay and has no errors
Also older excisting Photoshopfiles get this Error.
Saving Adobe Indesign and Illustrator files work fine. No problem saving files.
Yes did the "Security & Privacy" option, add it manually.
