After i installed adobe acrobat (don't know affect it or not) and worked in photoshop i got little problem... I've saved my work in pdf (without photoshop edit option), then in psd. And after that i checked psd file i realized then it is without layers, i can't edit it! I didn't have this problem before i adobe acrobat installation...
This settings didn't help:
maximize compatibility always
disable PSD and PSB compression
Still same problem...
Adobe photoshop 23.0.1.68
Adobe acrobat DC 21.007.20102
