So disappointing...

40 minutes of work down the drain because Photoshop crashes... I would share more but this is ALL I have... to work with... GONE!

You should be saving intermediately.

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop forum.

Crashes are usually caused by buggy video drivers (or dual GPUs in many laptops). It's really out of Adobe's control. In my experience Photoshop is rock solid. I haven't seen a crash in years.

That said, there is built-in crash recovery. You set the intervals in Preferences. However, note that for this to be activated, the file has to be saved to disk at least once. After a crash, Photoshop will reopen whatever you had open when the crash occurred.

Of course, Peru Bob gave the real answer: you should save incrementally as you work.
