Can't see psd preview icons since Sequoia update

I was thinking of a mouse for doing the right click but this is more a Windows term so please ignore my calling it a right click. On a Macbook trackpad it is a click with two fingers (also called a secondary click). On a MacBook a control (key) click is the same as a click with two fingers on the trackpad. By selecting the Change All option with the selected application you are making the change to every psd file.

I think you want to set the default application used to open a file with a psd file type because this has been lost in the Sequoia installation. In Finder right click a psd file, select Get info and this will open a new window with more file information. Go down to the section Open with and choose the default application you want to use, click on Change All… and this should change the icons for all psd files.
