I have successfully brought back Photoshop and Clip Studio pro from a “has stopped working error” several times. It’s saved me a lot of work and crying, so here’s what I do:
1) DO NOT HIT CLOSE PROGRAM. LET IT KEEP TRYING TO DO ITS THING.
2) Right click on the task bar and go to task manager (or Ctrl+Shift+Esc if your computer is especially slow). Go to the “Processes” tab and click on the “Memory” heading to sort by memory used. Then get rid of everything you recognize that is taking up a lot of memory (100,000+ K) by clicking on it and ending the process. Don’t end the frozen drawing program, obviously. Closing the programs this way is often more responsive than trying to “x” out of them since the computer is a bit overwhelmed at this point.
3) Right click on the process for Photoshop (or whatever program you’re trying to rescue) and set the priority to “Above Normal”
4) Wait, hope, and try not to cry.
5) When it’s back, SAVE THAT DRAWING BEFORE ANYTHING ELSE HAPPENS.
This has worked for me every time I get this error, Which is not rare since I work on giant canvases with a ton of layers. I don’t know if temporarily changing the priority of the process has any negative effect on the computer (I switch it back after the error goes away) but if anyone computer savvy has something to say against it, please add to this post. I only do this because I’m lazy at saving and don’t want to lose all my work. I have gone up to “High” before when I’m desperate, but I try to only use “Above Normal” to be safe.
