Hello ladies and gentlemen!) Go straight to the essence of the problem. Worked in the same .psd file, the source always remained normal and were opened too, until today, when opening, did not see that all the layers are merged, and the image is just black. The weight of the file has not changed. Is it possible now to pick up this file? Tried various utilities, but they did not help. Thank you.)
