When a memory card containing CR3 RAW files is inserted into my iMac running Mac OS Big Sur, the files show up with an Affinity icon in the filename, and automatically open with Affinity. How can this be turned off and show anion of the actual image so I can review all the images quickly. This has only just occurred using CR3 files . CR2 files are ok.
Thanks.
iMac 27″, macOS 11.3
I don't have My Mac handy, but it the RAW files are supported on your computer, you might see if setting Preview as the default application gets the thumbnails back.
You may want to try the free XnView MP. It will display previews of many RAW types.

Okay. The reason I suggested XnView MP is because you can view all of your .cp3 thumbnails at one time. I downloaded some sample R6 files…
Many thanks for the 'open up' advice - all ok and now opens up in Photoshop. it hasn't however changed the small icon (showing ps) under the picture when opening an sd card using the 'as gallery' view. This means I have to click on each file to preview rather than preview with the small icons as I could with CR2 files, and just scroll through the icon images quickly. (The small icon is present on all 'views')
Thanks. All successfully done, and all CR3 files open in Photoshop. It's the small icon PS below the preview (see pic) I need to change from ps, so that I get a small preview as I had with CR2 files. At the moment I need to open each file and rh mouse click to see what it is, with the small icon preview I can swiftly slide through the files to view.
Which Canon camera are the files from?

No, just opens up in preview. Still left with ps icon.
Click on a CR3 file in the Finder ONCE.
Select Get info from the File menu.
Drop down the Open with section of the Get Info window, and use it to select the application you want to open the file type.
Did you click and follow through with the Change All… button after changing the application to open the .CR3 files? I don't have Photoshop, and my default viewing application is Preview. I selected Affinity Photo just to get the Change All… button to appear in the following screenshot:
As it turns out, Affinity has its own camera raw library that often supports certain camera raw images before Apple.
