R6 not turning on, not work

[Gley]

I bought my Canon EOS R6 1 year and 6 months ago, I use it with a Meke adapter and a Canon EF 24-70mm f2.8 lens, it was working perfectly fine, but last Saturday when I was photographing a client, the camera suddenly turned off, the battery was 100% charged, I changed the battery that was 100% charged, and the camera did not work anymore, it does not turn on.
I already tested without the lens and without the adapter, and the camera simply does not turn on.
She is dead.
I'm desperate.
Thanks.

This sounds similar to your previous issue.  Was that issue ever resolved?  

Is this a new issue, like a repeat of the same old issue once again?
