Multiple issues after upgrading to Unity 2.01.09 from 2.01.08

Thanks, I have now reproduced this issue. AddressableAssetSettings.BuildPlayerContent() ends up calling PlayerBuildInterface.CompilePlayerScripts(), which unfortunately does not call IPreprocessBuildWithReport.OnPreprocessBuild(), which we rely on to generate the StaticPluginManager class.

I’m still looking into a way to fix this, but as a workaround you could try making Settings.PreprocessBuild() public, and calling it before calling AddressableAssetSettings.BuildPlayerContent():

FMODUnity.Settings.Instance.PreprocessBuild(BuildTarget.StandaloneWindows64, FMODUnity.Platform.BinaryType.Logging);
AddressableAssetSettings.BuildPlayerContent();

Could you put a breakpoint on EventManager.cs line 623, and compare sourceInfo with targetInfo? That may shed some light on the issue.

    if (!targetInfo.Exists ||
        sourceInfo.Length != targetInfo.Length ||
        sourceInfo.LastWriteTime != targetInfo.LastWriteTime)
    {
        if (targetInfo.Exists) // <------------------------------ Breakpoint here
        {
            targetInfo.IsReadOnly = false;
        }

This sounds like the issue reported in this thread. Can you try the solution suggested there?
