Visual Studio 2022: "Source control provider associated with this solution could not be found"

[audiamus]

Visual Studio 2022 Community Edition, 17.2.3

AnkhSVN build from source, June 3.

Starting up any solution in VS2022 with AnkhSVN source control pops up this message box:

---------------------------
Microsoft Visual Studio
---------------------------
The source control provider associated with this solution could not be found. 
The projects will be treated as not under source control.

Do you want to permanently remove the source control bindings from the projects?
---------------------------
Yes   No   Help   
---------------------------

Clicking "No" seems to bypass the problem and AnkhSVN appears to work.
