When I create (any) Relation between two classes nothing is displayed in the diagram editor.

Create Reference:
index.php/fa/42696/0/

Result:
index.php/fa/42697/0/

Any ideas whats going on or what I'm doing wrong?

Hi,
Do you see anything in the error log?
IIRC, this kind of symptom can happen when the Java helper classes which are used by the modeler can not be loaded and/or executed properly.

Thank you, yes there are log entries that seem to be connected to the problem:

I used Eclipse Installer to install a new 'Eclipse Modeling Tools' instance. The diagram editor works as expected. Comparing the installed packages with those of my regular development environment, I detected some differences in the Sirius versions Ecore is pointing to.

Updating Ecore resolves the issue.

Yes, Sirius 7.0 moved some internal classes around for increased modularity, but Ecore Tools depended on some of them.
Ecore Tools 3.3 is compatible with Sirius 6.x, but Ecore Tools 3.4 must be used along with Sirius 7.x because of this (https://git.eclipse.org/r/c/ecoretools/org.eclipse.ecoretools/+/185249).
