EOS R8 - Is Not Reading SD Cards

[comety]

Canon R8 cannot read SD cards that it was reading just fine for weeks. It is a new camera, and I cannot detect any damage when I peek into the card slot. I am using cards that are listed as compatible on the Canon site. I also reset the camera to factory settings. The full error message is "Card cannot be accessed. Reinsert/change the card or format card with camera."

I've seen a lot of errors posted on this site about the same issue but not for the R8 specifically. I just got the camera, so I'd rather not be sending it off to a service center so soon. Is there another explanation?

Hi, sorry, I moved on from the topic and didn't realize anyone still wanted to know how this turned out. I'm sure you already resolved your issue, but my resolution involved sending the camera to Canon to have it serviced. It has worked fine since then.

Unfortunately, one of my other R8s just developed a similar issue, except the error message states "no card in camera". So while the previous problem was that the camera saw the cards but could not read them, now the problem is that camera does not see the cards at all. I guess I will send this other camera to Canon to be serviced too.
