EOS Canon R6 mkIII Image write failure

[McNulty211]

I was shooting a wedding yesterday on a new R6 mkIII which I've used for a few weddings with no issues. I updated the firmware to 1.1.0 and was using it for the first time since the updating the firmware. 

I was about 30 shots into the day. I lifted my camera to find the viewfinder screen visible, showing what was through the lens but all the camera setting info and focus points weren't visible. I pressed the shutter button and nothing was working so I turned off the camera (did not remove the battery) and turned it back on and it was working as normally. 

I continued to shoot and then decided to check my camera and review an image and all of the images I had shot since turning the camera off where not viewable in the camera. I then turned off the camera (did not remove battery) and the screen said 'saving' 132 images. I let the camera sit for 45 minutes and it still said 'saving' with no change. 

I then removed the battery and checked the camera to find the images were still not showing on the memory card. I even checked the 101EOSR6 folder in both cards through the computer and no luck. 

I'm using Sandisk extreme pro memory cards (both a few months old) and was shooting images only, not in burst mode so there shouldn't have been any buffering issues. My memory cards were freshly formatted in camera at the beginning of the shoot and the images were set to RAW + JPEG. The write data was set to 'Rec to Multiple' and both cards have no images. 

I have yet to try any recovery software but I fear there was some sort of issue with the camera communicating with the memory cards. 

Any one have any issues like this before? Any thoughts?

Did you firmware upgrade because of an issue or just to get on the latest??  IMHO,  I've been in I.T. for 40 yrs.    if it isn't broken don't fix it, or at the very minimum, don't ever be anxious to update unless your trying to FIX an existing issue. No matter how much testing, especially with the complexity that exists in todays electronics, will there not be bugs.   I learned this the hard way way back in the DOS 6.2 days.....  and if your doing this for your living, the juice isn't worth the squeeze.

I updated the firmware just because it was available. The camera was working perfectly before the update (which may be a coincidence). I estimate I took 30,000+ images since with no issues until the update.

I brought the frezzing issue up to a Canon service tech a while back and he suggested getting new memory cards as they do have a lifespan. So far they R6 has been working well since getting new cards.

Some cards will show you its health data. This is from my Kingston MicroSD that I have used for one year. 

I used sdmon to get the data from the card.
