It looks like the umldiagrams are not loaded. Exactly how do you start argouml (and what version are you running)?

I have the same problem
I start argouml using java -jar argouml.jar

I downloaded now ArgoUML latest release from https://github.com/argouml-tigris-org/argouml/releases (ArgoUML-0.35.1.zip), extracted it to a directory in my linux system (within /home/euluis/Programs/), all files and preserving the folder structure (resulted in 54 files, mainly jar files and 2 folders).

Then, within said directory, from the terminal,
~/Programs/argouml-0.35.1 $ java -jar argouml.jar

And it worked... In specific, I added a class to the default class diagram, added a sequence diagram using 2 instances of that class one calling the other, saved the model and quit ArgoUML.

NOTE My java --version gives openjdk 17.0.8 2023-07-18

Maybe the directory you have the argouml.jar is missing all the other required jars in the release for it to work correctly?
