Darktable can't open files stored on NAS running latest kernel (6.3)

After updating latest kernel to 6.3.3 I have been unable to open files stored on a NAS. The photos show up in preview but opening the file for editing gives an error message that the file format is unsupported. Attempting to open the file again results in Darktable crashing.

My Darktable is a Flatpak install as I was having problems with the main repo install.

Switching to kernel 6.1 seems to have resolved the issue. Anyone know what has changed in the latest kernel to cause this? I don’t seem to have any other issues opening files from NAS in other applications.
