May be I can help you to debug. I need a hint how to setup the development environment for addon(s). Is there a step by step description?

I also re-downloaded the code. The icons are still missing. I'm on Win11 and Gramps 5.1.5.

Thanks, I will have a look on it.

I have read the link carefully and tried several suggestions. But nothing has helped. Only the CardView icons are not displayed. Can it be due to GrampsAIO German?
