Nik Collection breaks down Photoshop CC on Catania

I’ve recently installed the trial version of Nik Collection on my new Macbook running under Cataline 10.15.6. Whenever I try to use any of it as a Plugin from Photoshop CC (2020) it breaks down Photoshop completely. A red rectangle appears instead of the Nik window and I can only force quit Photoshop from there on. Any ideas why this might happen and how I can fix it? Is this a compatibility issue? Thank you!

Hi and welcome! I think it’s best if you go to and open a request with technical support. While some DxO staff are present on these forums, there is very little participation from the Nik Collection team.
