Get error in qtdepoly.targets at version 6.6.2 and 6.7

Larry K

When building a debug and release version with option "Run Deployment Tool" set to "Yes" getting this error:

1>C:\Users\lpk9012\AppData\Local\QtMsBuild\deploy\qtdeploy.targets(269,5): error MSB4023: Cannot evaluate the item metadata "%(Fullpath)". The item metadata "%(Fullpath)" cannot be applied to the path "Adding in plugin type generic for module: Qt6Gui". The given path's format is not supported.

Using VS2022 Enterprise 17.9.6

Works fine with 6.6.1 and before.

I get the error, too. After running the compilation again it goes away... until the next compilation at which again the recompilation helps temporarily.

Also happens in 6.6.3

    // Run windeployqt

    <PropertyGroup>
      <Cmd><![CDATA["$(QtToolsPath)\windeployqt.exe"]]></Cmd>
      <Cmd>$(Cmd) --list target</Cmd>

    <Message Importance="high" Text="Qt Deploy: $(Cmd)" />
    <Exec Command="$(Cmd) > &quot;$(QtDeployLog)&quot;"
          EnvironmentVariables="$(QtDeployEnv)" />

    <!--

    <ReadLinesFromFile File="$(QtDeployLog)">
      <Output TaskParameter="Lines" ItemName="QtDeployed" />
    </ReadLinesFromFile>
    <ItemGroup>
      <QtDeployed Remove="@(QtDeployed)" Condition="!Exists('%(Fullpath)')"/>
    </ItemGroup>

This part in the qtdeploy.targets is the cause.
Apparently the first few outputs of windeployqt.exe are lines like this:

Adding in plugin type generic for module: Qt6Gui
Adding in plugin type iconengines for module: Qt6Gui
...

before outputting one .dll/.qm file per line.

    <ItemGroup>
      <QtDeployed Remove="@(QtDeployed)" Condition="!Exists('%(Fullpath)')"/>
    </ItemGroup>

Since this part cant resolve these lines to paths, it throws the error.
That's the cause, but I'm also not good enough at Visual Studio/Qt magic to work around this.
Is there a way to inject a step into this targets file to filter the first few lines? Or just skip that step?

Edit: turns out the "--list target" parameter for windeployqt is specifically there to stop those
Edit: https://bugreports.qt.io/browse/QTBUG-122257 has been reported and fixed as of 6.8 apparently, so I guess the only fix is going to a newer Qt Version.
