TLDR: I've had two dead Sony SD cards in my R6 Mark II in a month. What is going on here?
For some back story, I've been using 128GB Sony M and Sandisk (primary and backup, respectively) in my R6 (original) bodies for 3 years and 600k frames. Not a single problem. No failures, no corrupt images. Nothing. They have been perfect.
This year I upgraded to R6 Mark II bodies now the 128GB cards aren't quite big enough to get through a long weekend for me. I upgraded to 256GB cards - Still Sony E and Sandisk respectively.
Less than 5000 frames into the new SD card and the camera card light freezes on and won't go off. Camera completely unresponsive. I have to pull the battery to turn off the camera. Re-inserting the battery and now the Sony card is dead. Unrecognizable in any camera or card reader I test it on.
I RMA the card to Amazon and get a replacement.
Fast forward to this weekend's wedding. Less than 1000 frames into the new replacement SD card and the exact same things happens. Frozen camera, remove the battery, now I have a completely dead card. It's the Sony again. Same camera, same card slot.
To note - I have an identical Sony 256GB card in the other R6 Mark II camera body and it has experienced no problems.
Any idea what is going on here? The two failures occurred from the same model/capacity Sony SD card (both from Amazon) in the same camera, and same card slot. I'm nearly a million frames into recording my pictures to SD cards and NOT ONE failure. Now I have two identical failures within a month of each other.
I don't think think this is random, but I can't figure out what is going on either. The SD card in question is below.

Nearly the exact same thing happened to me back in the fall. Two dead 256GB Sabrent V60 cards, both bought at the same time last summer from B&H - same batch number, etc. First one died Sept. 24 and the second Nov. 19th, IIRC.
Both times I did the RMA with Sabrent directly and they replaced both, no questions asked (after I sent in each to their RMA address), via direct ship to me from their Amazon Canada account. Replacement cards have different batch numbers. After the first one failed I bought another Sabrent 256GB V60 card and it has been fine, as have been both replacements (fingers crossed!!). I always shoot to both cards for backup so neither time lost any images, but for sure, this has been concerning. Since the first failure, for most of my events when I don't need super fast write speeds, I have been using Sandisk Extreme (non-pro) 256GB V30 cards in the second card slot instead of the same make/model in both slots.
Prior to the two card failures I've had a few quirky situations. I had around 30% of the images from a shoot corrupted on a PNY 128GB V90 card while the images on the mirrored card were fine (don't recall if I used the same make/model of card or something different). This happened in early Feb. 2023. I stopped using that card immediately after that incident, so not sure if it's a card or camera issue. Considering I have not experienced image corruption since then, I felt it was probably the card (and not the card reader because I tried a couple after I noticed the problem and it persisted). There have also been seemingly random situations where after inserting a card, the camera won't be able to read/recognize it. Thus far, this always resolves by re-inserting the card. This most recently happened a week ago with a Sandisk Extreme (non-pro) 256GB V30 inserted in slot 1 after a very long time of not seeing this problem.
I *think* but am not 100% sure that all or most of these problems have been with cards in slot 1, which I use as the default slot (the camera has a menu setting that allows you to set a priority card slot that it returns to every time if there is a card in that slot).
The first Sabrent 256GB V60 failure happened a couple thousand photos into an event, right in the middle and was a couple months after I bought that card. It was pretty much exactly as you described. I pulled both cards (to ensure the back up card wouldn't be affected if it was a camera fault) and kept shooting. Afterwards, the failed card could not be recognized in either slot or any card reader slots/devices on the computer. I couldn't even get to the point of being able to reformat it in camera or use Disk Utility on my computer. Second failed card was the same situation (in respect to trying to recover it).
I kind of didn't think it was the cards, though Sabrent is fairly new in the memory card scene. With your nearly identical experiences with failed Sony cards, I'm more doubtful it's the cards and think it's something with the camera. Bad card slot hardware? Bad software? Camera doesn't like fast cards (V60 or V90) when mirroring? I didn't take the camera to Canon because it seemed like too unrepeatable of a problem and they'd blame bad cards anyway. And now the camera is out of warranty...
Did you by chance photograph the back side of the cards with the batch/serial numbers? Where were the Sony cards made? China, Taiwan, somewhere else? I think a lot of these cards come out of a limited number of factories....
