That is just saying that the 21 file used Cadimage add-ons that you don't have loaded in 22.
It seems Archicad is starting OK - just not loading any files completely.
I am wondering if it has something to do with the Work Environment.
Load the standard template again but make sure you set it to use the Standard Work Environment.
If that doesn't work then I would try un-installing & re-installing Archicad.
Check it before you install the latest update and then install the update again.
At least this way you will find out if it is the update.
Then if still no luck, contact your local support centre (distributor).
