I’ve had and continue to have unreliable results with restoring Project files since introduced and the same with subsequent updates.
The first scenario: I edit a 16bit TIFF (3168 x 4752) straight out of Lightroom, I add multiple adjustments, Save As Project file, a few hours later after a reboot I reopen with the error as attached, then the Project file vanishes from the HDD.
The second the same as above, but the Project file remains unopenable.
The third, the file opens with a doubled-up preview as attached, a few seconds later, the preview resets to a single image as it should be, then the masks appear with the black and white, all normal, then a few seconds later the masks turns solid white with the adjustments applied to the whole image, the mask edits do not appear. This one I’ve experienced only with 1.3.2.
