EOS R5 Error 70 missing pictures on SD card

Hello, I'm encountering ERR 70 on my Canon EOS R5 with an RF 28-70 lens and original Canon batteries. The software is up to date. Initially, the error would briefly appear, but during a recent wedding shoot, 26 photos went missing from both SD cards in the middle of the sequence. I'm concerned about using the camera. Any advice on what steps I should take would be greatly appreciated.

Greetings,

This error might have more than one cause.

I'd recommend Canon OEM batteries.

Brand name CF Express B / SD cards and canon glass / adapters

Canon Knowledge Base - Error 70 displayed on an EOS Mirrorless Camera.

If the error persists and the above is confirmed, I would contact Canon and have the device inspected.  Nothing is worth missing shots or loosing photos during a paid gig.
