Dependency injection with a static logger, static helper class

Question

I have a static class which calls a static Logger class,

e.g

static class DoesStuffStatic
{
  public static void DoStuff()
  {
    try
    {
      //

This is a very simple way to "inject" the functionality of a static logger.

public static class Logger
{
    private static Action _logError;
    public static bool Initialised;

    public static void InitLogger(Action logError)
    {
        if(logError == null) return;
        _logError = logError
        Initialised = true;
    }

    public static void LogError(string msg, Exception e = null)
    {
        if (_logError != null)
        {
            try
            {
                _logError.Invoke(msg, e);
            }
            catch (Exception){}
        }
        else
        {
            Debug.WriteLine($"LogError() Msg: {msg} Exception: {e}");
        }
    }
}

public class MainViewModel
{
    public MainViewModel()
    {
        //Inject the logger so we can call it globally from anywhere in the project
        Logger.InitLogger(LogError);
    }
    public void LogError(string msg, Exception e = null)
    {
        //Implementation of logger
    }
}
