We get the error 500 when I try to open any project after upgrading:
In the logs we see the following:
Release : Any
Component : CA PPM PROJECT MANAGEMENT
This seems to be a custom field on Project object called TEST_FIELD that's no longer there in the view.
Go to Objects - Project - Attributes.
If the field is not there:
1. Recreate the TEST_FIELD attribute looking from another environment
2. Add it to the Edit views
3. Now try accessing the project again.
If the field is there:
1. Remove the field from Layout - Edit Views for Projects
2. Try opening the projects again
