A Javascript Error occurred in the main process (Navigraph Hub)


I installed Navigraph Hub and then I noticed, that it is not compatible with X-Plane 12.
I used the uninstaller of Windows 11 to uninstall navigraph hub.
After that, I still received the Javascript Error message as shown in the picture at every system start.
I ran a new installation of navigraph. I was only able to make a new installation by closing all of the Navigraph hub tasks in the background by using the Windows “Task Manager”, as explained by this thread:
Thread with the Javascript error and the installation using the Task manager

Now, I was able to have a “new and clean” installation on my PC again, but since I can not use it, I wanted to uninstall it and I went into the navigraph hub folder and ran the uninstall executable file of navigraph hub.
The uninstallation was successful, but at every start I still get the Javascript Error, as shown in the picture.
Any solution for this?
