problem causes:
IDEA 2018.3 was installed before, and then vm.option was modified. Later, the 2018.3 version was uninstalled and 2019.3 was installed. Can't start.
Solution:
rm -rf /Users/your username/Library/Logs/IntelliJIdea+corresponding version number
rm -rf /Users/your user name/Library/Preferences/IntelliJIdea+corresponding version number
rm -rf /Users/your user name/Library/Application\ Support/IntelliJIdea+corresponding version number
rm -rf /Users/your username/Library/Caches/IntelliJIdea+corresponding version number
Note:
If it still doesn't work, remember to uninstall the new version of IDEA you want to install, delete the above folder, and reinstall it.
