Thanks for the replied. Resetting the preferences was not solve the problem.
After upgrade os to catalina and adobe illustrator to 25.0 for a week, The result is better than the old one but it started to crash again on 29 Oct 2020.
Sorry to hear about the crashing. I know that's really frustrating. A few other users have also reported crashes on macOS and in later investigation, it was found due to some corrupt fonts.
I would request if you could try the steps shared in this help article (https://helpx.adobe.com/illustrator/kb/crash-with-ttf-font.html) and let us know how it goes.
