Updating Trek hanging -- unsynced personl treks

I am currently planning the next trip on a laptop. When I go to save the current navigation path a splash panel appears in the centre of the screen saying "Upating Trek .." but then this just hangs, have left it for over an hour .. still hanging,

In data managemer panel I have 2 unsynced personal treks. This seems to be associated with the 2 versions of the current trip I am planning. They remained unsynced even after hitting sync button.

I have also shut down, rebooted, done all that .... still same problem,

Also just noticed that in the data panel the treks & folders are not showing .... can only see places, tack logs and addresses.

Am using the current version of program -- and Topo Maps 2023.

Any helpful suggestions appreciated,

Cheers

Stephen
