Issue when adding an integration

I had ‘Niko Home Control’ installed in the past, and working.
I had to re-install it.
first I removed all the entries from the YAML files, and the folder ‘custom_components\nhc2’
I used the HACS integration, re-downloaded it, and tried to add it again.
Now I get this error :
image
“Config flow can not be loaded”
The folder under ‘custom_components\nhc2’ re-appeared, so ‘something’ has happened.

And this is in the log :

2022-01-07 10:50:03 ERROR (MainThread) [homeassistant.components.light] Setup of platform niko_home_control is taking longer than 60 seconds. Startup will proceed without waiting any longer.

How can I solve this ? or find some additional loggin ?
