App store crashes on startup; preferences apple id pane cannot load

Greetings Sleepy_Tiger,

Since the issue is isolated to a single user account, begin by removing any login items for that account.

Remove login items to resolve startup problems on your Mac

"Remove login items to resolve startup problems on your Mac

Login items are apps that open automatically when you start up or log in to your Mac. Occasionally, a login item may cause a blank blue screen at startup or other problems. You can test your login items to see if any are causing startup issues on your Mac.

Note: To print these instructions, press Command-P.

1. On your Mac, choose Apple menu  > System Preferences, then click Users & Groups .
2. Click your account name below Current User, then click Login Items at the top of the window.
3. Make a list of the login items—you’ll need to remember them later.
4. Select all of the login items, then click the Remove button .
5. Choose Apple menu > Restart.
6. If this solves the problem, open Users & Groups preferences again, add the login items one at a time, and restart your Mac after adding each one.
7. When the problem occurs again, follow the steps above to remove only the last login item you added."

Take care.
