Okay - I have had success two shoots in a row. Key: laptop at 100% power and plugged in to charger. Camera: using a DC battery-less adaptor (such as https://www.amazon.ca/Adapter-Gonine-Coupler-Battery-Replacement/dp/B01D68YXOQ/ref=sr_1_1_sspa?crid=1HPHGAAYIHAO5&keywords=e6+adaptor+dc&qid=1676822942&sprefix=e6+edaptor+dc%2Caps%2C148&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyTjZWTzdVT0tFV0ZIJmVuY3J5cHRlZElkPUEwNzMzNDg5MjZNQ1JKQlhPVzc4UyZlbmNyeXB0ZWRBZElkPUEwNjIwMTcyWUxYR0pGOVEzNzFGJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==)

This takes the charging aspect of the USB C out of the picture.

Also updated recent Lightroom so it doesn't need the Rosetta(?) emulator.

So far so good. It's one more cable for the power on camera, but I have yet to have an issue.

This for me also answered why it was intermittent, as it could have been how charged batteries were in laptop or camera.

Still working to confirm, but this is the biggest breakthrough I've had so wanted to update here.

Maybe one of the problems people are having is the laptop tries to charge off of the camera? I believe some laptops can charge via USB-C, and maybe it sees it as a power source.

No, USB PD has a discovery and handshake protocol for that. Unlike all the USB charging that came before, you can’t just start charging.

And that is also one of the reasons people have issues with USB PD, the negotiations fail for some reason and no charging happens.
