Create VS extension with Analyzer and Options Page for Visual Studio 2022 - visual-studio-extensions

Question

I am trying (and failing) to port a Visual Studio [extension][1] to the latest version of Visual Studio.
The extension provides a set of Roslyn analyzers and code fixes as well as an options page to configure some aspects of the analyzers' operation.
A reduction of the problem can be demonstrated with the following steps:
Follow instructions [here][2] to create an analyzer
Follow instructions [here][3] to create an options page
Now try to combine the two into a single VSIX.
I have tried starting from #1 and then adding relevant items from #2 and vice versa. To no avail.
Unfortunately the two samples produce different project types, and target different .NET frameworks which doesn't simplify things.
Depending on which sample I start with either the analyzers or the options page are not loaded.
Here is what the .vsixmanifest looks like (started by using the options page sample and then adding in the analyzer code):
<PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">

<Asset Type="Microsoft.VisualStudio.Analyzer" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%;PkgdefProjectOutputGroup|" />
</Assets>
</PackageManifest>
How can I debug why a specific asset defined in the .vsixmanifest file is not being loaded?
Would be great to see a sample where these are combined.
Peering into the compiled *.vsix (as zip file) it looks like an error in the auto-generation of the .pkgdef / catalog.json file, depending on what kind of project I start from. One or the other is missing from here despite having an identical vsixmanifest. For example catalog.json looks like this (note that the options page is missing):
