Stitched tif file created by PTGui is not opening after 13.7 update in photoshop 27.7.0

[Ashok Mansur]

After installing 13.7 tif files are not opening in PS 27.7.0 on Mac OS Sequoia 15.7.7 I get the following message 

Could not open "P0001022 1 Panorama.tif" because the file format cannot parse the file.

If I save it in .dng and .psd it'll open but not in tif 

stitched  .tif file is 1.25GB

Hi Ashok,

I've seen those errors happen with Photoshop randomly when loading files
in Photoshop from a network drive. The file is not necessarily corrupt.

Which settings did you use in PTGui (see the Settings button in the
Create Panorama tab)? You could try another compression setting and see
if that helps.

You can also try loading the tiff file back into PTGui and see if it is
indeed corrupt.

If you think there's a problem in PTGui, could you share your tif file
with me at sup...@ptgui.com? You might try if the problem also occurs
at smaller sizes so you don't have to upload such a large file.

Kind regards,
