Do you get the crash reporter dialog?  If you haven't done so already, please submit all Crash Reports along with your email address: https://helpx.adobe.com/photoshop/kb/submit-crash-reports.html That will help us diagnose the crash.

When Photoshop crashes, this is the first thing to do, try resetting your Photoshop preferences. Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) immediately after launching Photoshop. You will be prompted to delete the current settings. You can also reset preferences upon a quit if Photoshop is running by going into General Preferences>General>Reset on Quit.

Go to Preferences > Performance... and uncheck Multithreaded Compositing - and restart Photoshop.
Still crashing? 
Go to Preferences > Performance... click Advanced Settings... and uncheck "GPU Compositing" - then restart Photoshop. Still crashing?  

Hello, sorry to hear that, could you please post the contents of Photoshop's Help>System Info... menu, so that we get to know your OS, its version, the exact version of Photoshop you are running, the date of the GPU driver, etc.

most issues occur because of GPU issues, try first to check "Deactivate Native Canvas" in the menu Edit/Preferences/Technology preview (Pc) or Photoshop/Preferences/Technology preview (Mac), then restart Photoshop.
This is not a fix, but rather a way to check if the issue appears only with the new technology, and should be reported to the Ps team.
