After updating LrC to 14.4, and then using super resolution on a RAW file, then exporting it to Photoshop, Photoshop starts, opens, but no file appears and no menu items or tools work in Photoshop. Task Manager in Windows is necessary to close Photoshop. The same procedure is applied to the same RAW file, after resetting the RAW file, but without super resolution or denoise being applied. The RAW file is sent to Photoshop, Photoshop opens and works as usual. These procedures were applied to several other RAw files with and without super resolution applied. The results in Photoshop were repeated as above. Use super resolution on a file in LrC then go to Photoshop - Photoshop will not function. Solution : stay with LrC 14.3.1 if you wish to use Denoise that works.
