Self-contained, trimmed .NET 9 executable "can't find framework" when run

I'm attempting to publish a project with two NuGet dependencies (one with native libraries) as a single-file, trimmed executable. 
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net9.0</TargetFramework>
        <RuntimeIdentifier>win-x64</RuntimeIdentifier>
        <PublishTrimmed>true</PublishTrimmed>
    </PropertyGroup>
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net9.0</TargetFramework>
        <RuntimeIdentifier>win-x64</RuntimeIdentifier>
        <PublishTrimmed>true</PublishTrimmed>
    </PropertyGroup>
I am using the following profile with the command-line dotnet.exe publish $FOLDER_CONTAINING_PROJECT --no-build -c "Release" /p:PublishProfileFullPath=PATH_TO_PROFILE --self-contained: 
    <PropertyGroup>
        <PublishDir>SOME_DIR</PublishDir>
        <PublishProtocol>FileSystem</PublishProtocol>
        <_TargetId>Folder</_TargetId>
        <PublishSingleFile>true</PublishSingleFile>
    </PropertyGroup>
    <PropertyGroup>
        <PublishDir>SOME_DIR</PublishDir>
        <PublishProtocol>FileSystem</PublishProtocol>
        <_TargetId>Folder</_TargetId>
        <PublishSingleFile>true</PublishSingleFile>
    </PropertyGroup>
but running the finished artifact produces: 
PS D:\fh\artifacts\localdeploy\rel\bin> .\fhmodmgr.exe
You must install or update .NET to run this application.

App: D:\fh\artifacts\localdeploy\rel\bin\fhmodmgr.exe
Architecture: x64
Framework: 'Microsoft.NETCore.App', version '9.0.0' (x64)
.NET location: D:\fh\artifacts\localdeploy\rel\bin\

No frameworks were found.

PS D:\fh\artifacts\localdeploy\rel\bin> dotnet --list-runtimes
Microsoft.AspNetCore.App 9.0.6 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 9.0.6 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.WindowsDesktop.App 9.0.6 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
PS D:\fh\artifacts\localdeploy\rel\bin> .\fhmodmgr.exe

Microsoft.WindowsDesktop.App 9.0.6 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
To clarify: 1) Aren't self-contained executables supposed to not require .NET to be installed in the first place? 2) Given Microsoft.NETCore.App >= 9.0.0 x64 evidently is installed, how can it not be found? 3) Is there something incorrect with either the project or publish settings that would prohibit this from working?

Not using a publish profile (moving any needed directives into the project file) doesn't seem to change a thing. This is the output running with COREHOST_TRACE on. https://gist.github.com/fkelava/b28ca32ffadd1779a1af81d2360fd78d Why exactly does it think the .NET location is the folder I'm running it in? How does that work?
