Dataset missing in Excel

[Petsnell]

After what seems to be an update of Excel to (Version 2305 Build 16.0.16501.20074) 32-bit with the new feature for "Insert Table", one of our datasets mysteriously dissapeared from the list. I am not aware of any other changes, and the error message when I try to update existing connections is inserted below.

Has anyone else experienced this or may provide suggestions on how to solve? When I use an older Excel, (Version 2208 Build 16.0.15601.20742) 64-bit, everything still works like a charm... The "Insert Table" function is not available there.

Such a silly mistake - the preview pane only shows a handful of datasets, I had to search and press enter in the search field to find the one I assumed missing...

However, this does not explain the error message when I try to update.
