With PS 2022.4.1 my nik filters are not longer working. Nik opens from within PS, I apply the filter but when I click OK and would expect the filter to process the image creating a new layer and mask in PS, nothing happens. No filter applied, no new layer, nothing. This does not occur in Lightroom nor with PS 2021.2.8.
This occurs with both Nik3 and Nik4 filters. Also, when the images is processing in Nik the status far flashes a solid red bar off and on. This is a separate issue.
You're going to have to take that up with Nik. Plug-in's often run into issues as PS is updated and the plug-in vendors have to update their software accordingly (and yeah, I'm speaking from frustrated experience as a plug-in developer).
Anyway, there isn't anyone here who can help you if the plug-in's need to be updated for a newer version of Photoshop.
