Throwing "Failed to execute weaver" exception on 1 (out of 19) VB project

[BRR-LASERS]

The project that is failing is the one where I implement the Attribute(s) that inherit from MethodBoundaryAspect.
All of the projects are VB, Framework 4.8.
When I do a rebuild solution (Visual Studio 2022), I get this exception:

Error: Fody: An unhandled exception occurred:

I immediately do a build and the project succeeds. I also have MethodTimer installed in that same project and it seems to be fine.
I have insured that the FodyWeavers.xml has the proper entries and that the (old style) project file has the vb references.

What am I missing?

After refactoring and moving the Attribute definitions to their own project AND giving that project an empty FodyWeavers.xml for that project AND correcting some obvious issues in the old format VBPROJ file for the one that's failing, now I'm getting the following:

Error: Fody: An unhandled exception occurred:

Same line numbers, but the message now says:
Unable to find variable reference for storage.

I'm kind of at wits end....
