Hold down the Option key, and while doing so, click on Go > Library. Please move the following items from the Library folder to an easily accessible destination, such as the Desktop.

Preferences/ByHost/com.apple.Safari.plist Preferences/com.apple.Safari.Extensions.plist Preferences/com.apple.Safari.LSSharedFileList.plist Preferences/com.apple.Safari.plist Prefereces/com.apple.WebFoundation.plist PubSub/Database Safari (Not the application – a folder named Safari). SyncedPreferences/com.apple.Safari.plist Once you have moved the items listed above, all of your Safari extensions will be removed, your bookmarks will be deleted and your settings and preferences will be reset. However, Safari will no longer crash on startup. If you decide to reinstall the Safari extensions that you lost, make sure to reinstall them one at a time. This prevents the accidental reinstallation of the extension that initially caused your Safari to crash. If you want to restore your lost bookmarks, simply open Safari, go to File > Import bookmarks, navigate to the file named ‘Bookmarks.plist’ in the Safari folder now located on your Desktop (or wherever you moved it), and import your lost bookmarks. Once done, you can delete all items you previously moved.
Solution 3: Delete all the files in the Safari folder in the Library,
Quit Safari. Go to User > Library > Safari. Delete all of the files in Safari. Don’t worry, as deleting the files in this folder won’t create additional Safari-related problems. However, be aware that deleting the files in the Safari folder will result in all your bookmarks being deleted and Safari settings and preferences being nullified, then reverted to their factory defaults.
