How connect to Puck.js on Windows 10 Desktop with Creators Update?

Ok, installing WinUSB again with zadig, then reboot, with CRS 4.0 module plugged in.
Then starting native Web IDE.

This is the console log:

Then click the yellow "Connect/Disconnect" field, but only COM1 is avaliable.

When choosing this, connection becomes green and status bar says CONNECTED TO PORT COM1 .
Console log adds:

Web Bluetooth available, but Windows Web Bluetooth is broken in <=60 - not using it
>>> Connecting...

Found a prompt... great!

No noble starting scan ...
In the communications settings, "Connect over Bluetooth Smart (BTLE) via 'noble'" is enabled.
I did not change anything there.
What more can I check/do now?

Thank you very much,
