Preview not saving edited photos (JPEGs) on MacBook running OSX 14.0 (Sonoma)

It seems that since updating my MacBook Pro (2019 16") to the latest version of OSX (Sonoma 14.0), the preview application refuses to save any photo that has been edited, presenting the following (rubbish and unhelpful) message: "The document xxx could not be autosaved" followed by "Your changes will not be saved until the problem is resolved. You can also duplicate the document or discard your changes to close it." However, even if I duplicate the file, the same erroneous message appears.


There is no reason why these files cannot be edited, as immediately prior to upgrading to the new OSX, it worked perfectly well, as expected on other similar files.


So basically, Preview now appears to be useless for making any edits to any photo (JPEG) files.


Thanks guys!

I upgraded to 14.3 2 days ago, and my problems (color only, I haven't really used greyscale - however the problems I was experiencing were the SAME) - 14.3 seems to have solved the problem and it's apparently an important security update.
