When I try to run my project, I get the following error:

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Psi.Media_Interop.Windows.x64, Version=0.18.72.1, Culture=neutral, PublicKeyToken=null' or one of its dependencies. 

Attempt to load an unverifiable executable with fixups (IAT with more than 2 sections or a TLS section.) (Exception from HRESULT: 0x80131019) ---> System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Psi.Media_Interop.Windows.x64, Version=0.18.72.1, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

(Exception from HRESULT: 0x80131019)

The workaround I've found is to include the following in my .csproj file:

    <Content Include="$(NuGetPackageRoot)/microsoft.psi.media.windows.x64/0.18.72.1-beta/lib/net472/Microsoft.Psi.Media_Interop.Windows.x64.dll">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>

Adding the following didn't work:

<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>

When I use dotnet run to run my project, it fails with the same error the first time, and it starts working again the second time. I'm assuming dotnet run somehow copies the dll over on the first run. Not sure why it fails every time on Visual Studio without the workaround above.

Any pointers would be appreciated!

Can you say a bit more about what kind of project you are trying to run? Is it a .NET framework project? Check that your .csproj is in the "new" SDK style: https://stackoverflow.com/questions/63055430/how-to-create-an-sdk-style-net-framework-project-in-vs

It’s a multi-framework project that targets net472 and net7.0. This error only happens for net472. Here’s a snippet of my csproj file (which I believe is already the new sdk style):

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFrameworks>net472;net7.0</TargetFrameworks>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <PublishSingleFile>true</PublishSingleFile>
    <RuntimeIdentifiers>win-x64;linux-x64</RuntimeIdentifiers>
    <SelfContained>true</SelfContained>
    <Platforms>x64</Platforms>
  </PropertyGroup>
…

  <ItemGroup Condition="'$(TargetFramework)' == 'net472'">
    <Content Include="$(NuGetPackageRoot)/microsoft.psi.media.windows.x64/0.18.72.1-beta/lib/net472/Microsoft.Psi.Media_Interop.Windows.x64.dll">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
  </ItemGroup>
…

Note that instead of using PublishSingleFile for net472, I use Costra.Fody.
