Which Adobe app are you using?
Your system should NOT be crashing frequently. That's not normal. Please ensure that your computer exceeds min-system requirements for CPU, GPU, Hard Drive and RAM. An inadequate computer will not provide you with a good user experience.
Second, you should protect your work by making redundant backup files on your primary hard drive & saving files often with Ctrl / Cmd + S. On big projects, I make several backup files so I can revert to previous versions if needed. You can never have too many backups.
