Are you talking about changing to a Win11 PC or updating the old PC to Win11?
My old PC updated itself from Win10 to Win11, this did not affect Pathfinder Office in any noticeable way. And there have not been floods of people complaining so smooth operation when Windows updates is probably common.
There were Windows Mobile Device Center (WMDC) problems which blocked USB connections to Windows Mobile devices, but those issues started before Windows 11 came along, and there's a Trimble Support Note which describes a step-by-step solution to get WMDC working again.
