Affinity Export and Save As: An Error Occurred While Exporting to:

[RCPhotos_FineArtAmerica]

Mac Studio M1 Max

Affinity Photo 1.10.5

Importing image file from LaCie set to RAID 1 

Transitioning from Windows to Mac. 

After opening an image file, and working the image or just opening and Exporting it, I am confronted with this window:

And this happens regardless I am using the RAID configuration or the Copy of this NAS. It is configured NTFS:

And as you can see even after unlocking the drive, it won't allow export or Save As. Even after running Clean My Mac X and  checking 'Repair Disk Permissions' this has had no effect. 

 

At a loss and need to get work done if anyone can provide the best approach I'd be most grateful

Copy the file over to your local system disk and then open that from there, also after making any changes save it on the local drive and afterwards copy it on your external drive. - See related ...

I am not sure this is still true but it used to be that Macs could not write anything to NTFS volumes unless a third party utility was installed, I think as an extension to Disk Utility or some such.

Can you write files to the NAS from other apps on your Mac?

Probably the OP has some MacOS NTFS driver software like the one from Paragon or Tuxera etc. installed, or maybe it was already bundled by the drive manufactor.
