Canon and Epson printer plug-ins missing in Photoshop 22.0.0

[Krakatos]

I just updated to version 22.0.0 of Photoshop (on Windows 10), and now my Canon Printer Studio Pro and Epson Print Layout plug-ins are no longer available from the File / Automate menu. What gives? Is there a way to re-enable the plug-ins, without re-installing them, and re-creating all my custom profiles and settings from scratch? Please tell me there is.

It seems that all that's required is to copy the contents of:

C:\Program Files\Adobe\Adobe Photoshop 2020\Plug-ins

...to:

C:\Program Files\Adobe\Adobe Photoshop 2021\Plug-ins

I don't know why the installer couldn't do this automatically.

There is nothing in the 2020 plug in folder
