On which functions and/or steps Photoshop crashes?
What steps you've tried to solve the issue?
Please try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.
If you're unable to access Preferences and PhotoShop crashes before that, please go to the location C:\Program Files\Adobe\Adobe Photoshop 20xx. Then rename the Sniffer.exe to Old.Sniffer.exe and try launching Photohsop again.
Another try it to turning on the option »Deactivate Native Canvas« (Photoshop > Preferences > Technology Previews) and restarting Photoshop.
If this doesn't help we need more informations about your system as @Bojan Živković wrote.
Is your system up-to-date? Check if there any patches and updates are available, especially for the graphic driver. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.
