Assign color profile vs proof setup

[Andygeol]

Confusing problem. I use a calibrated monitor and have always proof matched paper via View>Proof setup>Custom>icc profile of a particular paper, then used adjustment layer to get a better match. This is now not getting me close to what is coming out of my printer. What I have now discovered is that if I go to EDIT> Assign Profile>Profile (icc of the paper), the monitor and print are a VERY close match.

I have always been told that Edit asign profile should be the original colorspace the image was captured in ie Adobe1998. This ensured that what came out of the camera and what was on the screen would be a close match.What has gone wrong? Is it User error or has PS changed?

I use Win 10, PS CC ver 23.4.1

Thanks to all for the replies and suggestions.

I uninstalled and reinstalled PS and that has done the trick.

Although I know my own colour management workflow is not perfect in the eyes of the experts, it has always been pretty good at matching prints to monitor so my 'gut feel' that  something was off with PS was correct. It may have been a combination of my last monitor profiling and an update but I'm no expert. In any case things are back up and running.
