Hi,
> I checked the version of Access and it shows: 16.0.18623.20116
Where did you check the version? You should check it on the File - Account page, NOT from the About Access button and dialog, because this is not reliably up-to-date.
Which update channel do you see on the File - Account page? The build you stated would point to "Current Channel (Preview)".
> How do I get 16.0.18623.20156 to install?
On File - Account click the button Update Options and choose Update Now.
If that doesn't help with your import problem, you can test the opposite and go back to a previous version of Office/Access.
Servus
