Trezor one connected but not showing accounts on different laptop

My Trezor one works fine with my chromebook, showing all accounts and balances, and updated firmware today too.
However when I connect it to my windows laptop, although recognised as connected it shows none of my accounts and looks like a brand new wallet. It is definitely connected as it asks for my PIN, which works without a problem.

(Issue is not related to the firmware update - it hasn’t worked on the other laptop for over a week now)

Any ideas please ??
