Brand new Canon 5d mk iv will not tether to lightroom classic on my PC, 6d works just fine

Just a brand new Canon 5d mk IV yesterday. I went to do the microadjust on  my lenses with Lightroom in tethered mode. I get a PC icon on my 5d display and a "no camera detected" message on my laptop.

So I updated the 5d firmware to the latest version, aas well as Lightroom. Nothing changed. 

I did the microadjust for all my lenses just 2 days ago with my 6d, with no issues with Lightroom using the tether function.

I rarely use the tethered function, but I would like to have it available to use just in case.

I'm stuck.

What is the version NUMBER of your Lightroom? Do not use words like "latest" or "up-to-date"

LR is 10.0 release

RAW 13.0

5d firmware 13.0

It's working now. 

I updated LR & Windows in last couple of days. So maybe that was it.
