A family of Microsoft relational database management systems designed for ease of use.
Well, not sure this would help. But, a second and third reboot got the access database to display as it did before. Windows 11 is a nightmare. OneDrive is a nightmare. Both of these are the worst pieces of software MS has ever released. I will not hold my breath that it is fixed permanently because I am sure in time I will be fighting with some other stupid thing that this OS has done to me. Thanks for the feedback, but truly can't say what the problem was (or will be).
