Missing dll on Azure App Service deployment

I'm trying to deploy my web API to Azure App Service, using code deployment to Linux server from GitHub actions The solution has this structure (not its actual solution name, I can't reveal that part)

/AppAPI
    AppAPI.sln
    /Api
        Api.csproj
    /Data
        Data.csproj

/AppAPI
    AppAPI.sln
    /Api
        Api.csproj
    /Data
        Data.csproj

(Yes, weird, I know, but I can't change it now) The solution builds and deploys to AAS just fine, but gives this error in the logs: The application 'AppAPI.dll' does not exist. Which is not correct as the publish output assemblies are Api.dll and Data.dll Then, I went to the configuration panel and added dotnet Api.dll as the startup command, and re-ran the app, which then gives me: The application 'Api.dll' does not exist. Opening AAS's host SSH console shows that Api.dll does exist in ~/site/wwwroot (which also looks identical to the local publish output), so I truly have no idea what is happening, and would greatly appreciate any help

The log stream (image #1) and the last few lines of the docker logs at /api/vfs/LogFiles (image #2)

Docker isn't used, I'm using the deploy code option rather than deploy container The deploy job is as so

  deploy-api:
    name: Deploy App Service
    runs-on: ubuntu-latest
    
    env:
      APP_NAME: 'app-api'
      DIR_PROJ: ./AppAPI

    steps:
    - name: Checkout
      uses: actions/checkout@v4
    
    - name: Build and publish
      working-directory: ${{ env.DIR_PROJ }}
      run: |
        dotnet restore
        dotnet build --configuration Release
        dotnet publish -c Release -o publish

    - name: Login to Azure
      uses: azure/login@v2
      with:
        creds: ${{ secrets.AZURE_DEPLOY_CREDENTIALS }}

    - name: Azure deploy
      id: deploy-to-webapp
      uses: azure/webapps-deploy@v3
      with:
        app-name: ${{ env.APP_NAME }}
        package: ${{ env.DIR_PROJ }}/publish

  deploy-api:
    name: Deploy App Service
    runs-on: ubuntu-latest
    
    env:
      APP_NAME: 'app-api'
      DIR_PROJ: ./AppAPI

    steps:
    - name: Checkout
      uses: actions/checkout@v4
    
    - name: Build and publish
      working-directory: ${{ env.DIR_PROJ }}
      run: |
        dotnet restore
        dotnet build --configuration Release
        dotnet publish -c Release -o publish

    - name: Login to Azure
      uses: azure/login@v2
      with:
        creds: ${{ secrets.AZURE_DEPLOY_CREDENTIALS }}

    - name: Azure deploy
      id: deploy-to-webapp
      uses: azure/webapps-deploy@v3
      with:
        app-name: ${{ env.APP_NAME }}
        package: ${{ env.DIR_PROJ }}/publish

Yeah, it's net6, but AAS still has an option for it and the runtime exists as normal

run dotnet --info on the app service

If I run dotnet Api.dll on the server console there, it does run properly by the way (except for the fact that it crashes because I forgot to allow the app through the database firewall)

Initial deployments always had this issue, but at one point it started working (with unrelated errors, see https://discord.com/channels/143867839282020352/156079822454390784/1314127421464772678), but then somehow it regressed and no longer worked

Deploying my web API to Azure App Service is giving me this in the logs:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.EntityFrameworkCore.Relational, Version=7.0.20.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.EntityFrameworkCore.Relational, Version=7.0.20.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

My current hypothesis is that it's caused by the app running on .NET 6, but using EF Core packages at version 7.0.x, if so, any ideas on how to fix this short of upgrading the .NET version?
