After updating to .net7 rc1, I am getting occasional crashes of the IIS process after compile has finished.

I have shadow copy enabled, and this is in the build file, so that iis properly reloads after my build.

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="del /q $(ProjectDir)app_offline.htm" />
  </Target>

  <Target Name="PreBuild" BeforeTargets="PreBuildEvent">
    <Exec Command="echo &quot;offline&quot; &gt; $(ProjectDir)app_offline.htm" />
  </Target>

@davhdavh can you provide a stack with symbols or a full dump? From the partial stack, this looks like a managed exception potentially coming from user code.
