You can upgrade to PSE 2025 which can install camera raw 17 using Help>Install Camera Raw or you can

replace the camera raw plugin in PSE 2023 by following the directions in this thread:

Another alternative is to use the free Adobe DNG Converter to convert the Canon R5 mk2 cr3 files to DNG copies which then PSE 2023 will open:

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
