Wio Terminal WiFi errors

Unfortunately I still get errors from the WiFi Scan sketch.
(For good measure I repeated the re flash process wuth no errors!)
This is the output:

Device reset sequence finished!
Cannot initialize ESP-AT Lib!

[E][WiFiGeneric.cpp:477] mode(): Could not set mode! -1

Can you suggest what I may have missed?
Thanks
