I try to understand why RTE doesn't work on my application.
Therefore, I created a new standard .net 7 Blazor-server application, followed the steps, and came to the same conclusion. Same problem displaying the RTE as the screenshot shows.
I found some example projects, they work. So after I verified them with my project, I can't seem to find why I have this issue.
I now call your help to help me solve this.
At GitHub I have my test project
Naturally, without my Licence key, but that was there when I tested it.
I saw that it made no sense for the end result whether the key was there or not,
I hope I overlooked something stupid, but important.
Thank you for helping me.

I was able to fix it, as it was a problem in the .css path
