Wingpanel non functional in permanent crash loop

[canopusStar]

What Happened?

Wingpanel takes two minutes to load at start up.

When it loads, clicking on any right hand menu (power/BT/Notifications) it crashes it and hangs all open apps.

Wingpanel restarts, apps become responsive but Wingpanel crashes again when it is clicked.

Repeat until all apps hang, Terminal reboot required.

I tried to reinstall desktop and wingpanel. If I do not click Wingpanel system is fine.

Steps to Reproduce

1. Login
2. Wait for Wingpanel to load (up to two minutes)
3. Click notifications or power or bluetooth
4. Wingpanel freezes (1 minute)
5. Wingpanel restarts
6. Open apps become responsive again
7. Click Winpanel - freezes and hangs open apps
8. Wingpanel restarts - Applications will open clicking Wingpanel, clicking power or notifications will crash it again

Expected Behavior

Wingpanel has deteriorated since upgrading to 6.1

OS Version

6.x (Odin)

Software Version

Latest release (I have run all updates)
