LP5012EVM: GUI not be able to talk to the EVM board

Team,

Using the LP5012 with USB2ANY and LP50xx GUI SW :
  -The latest GUI SW is used (taken from this E2E post).
  -The USB2ANY firmware update has been done.

The GUI does not seem to be able to control the LP5012.

-Is the issue HW or SW?
-How to fix it?

1) When entering in the GUI, I can see that USB2Any is detected… but… I got an error message
pop on the bottom left: “Couldn’t load registers”:

2) When I select « Quick Start », the Bank Settings panel is displayed, but I have an error
message pop « Couldn’t write register DEVICE_CONFIG0 » in the bottom left:

3) Still on the Bank settings panel, if I select the LED 4 for example, I have « Couldn’t write
register DEVICE_CONFIG0 »

4) I have similar issue on each Item of the Main panel:
