Hacs integration "Arris" failed to remove

I removed a hacs integration manually, but I think it failed.
Because now i every time get following error message
Logger: homeassistant.setup
Source: setup.py:189
First occurred: 17:35:58 (1 occurrences)
Last logged: 17:35:58

Setup failed for arris_dcx960: Integration not found.

Can someone assist me in removing the Arris integration completely.
Also tried to remove in HACS but this is not working!
When I click on the remove button, then nothing happens.

So I think I have to remove it manually.
