R6III + Godox Flashes = Error 70 --- anyone else experience this problem?

Hello everyone.
Ever since getting the R6 Mark III about a month and a half ago, I've been having this problem happen with close to 100% repeatability.

Whenever I use more than one Godox Flash. And trigger both of them. The camera freezes, usually stuck displaying the moment of shutter release, sometimes I got an error 70. With testing I've managed to narrow it down to the specific scenario of where the focus mode is in SERVO.

So whenever the camera is in SERVO, and I am triggering more than one GODOX flash the camera freezes. Every time.
I'm using the latest GODOX V480c V100c and X3c trigger. In various combinations their effect is always the same.
As soon as I turn on a second flash while in SERVO, the camera freezes on the image - it gets saved in the camera,
though I've had a few that appear to not have a proper date.

I wrote to Godox - they said they don't have the camera for testing yet. And thanked me for the feedback.
Amazing.
What I am afraid of, is that this is some kind of new Canon cripple hammer thing.
Though I'm sure they can fix it with firmware updates. As soon as they get to it, hopefully soon.

Has anyone else gotten the R6III camera and has encountered or can test out this issue?

Thanks.
