NIK 8 collection refuses to run as plugin in my Affinity Photo 2

@bellnier I have provided a link to a previous thread, which you may find useful:

Nik Collection 8 and Affinity Photo 2

I’m running the latest version of Affinity Photo2 and have recently installed Nik Collection 8. The plugin appears in the filters drop down menu along with NIk Collection 7. When I come to use Nik 8 a message pops up and disappears too quickly for me to read and returns me back to Affinity editing screen. I can still use Nik 7 as normal. Is there something I’m missing? How can I resolve it (bearing in mind I’m not terribly tech savvy)
