                try
                {
                    if (_currentSession != null)
                    {
                        _...

                        if (disposeEventSessionImmediately)
                        {
                            DisposeEventPipeSession();
                        }
                    }

                    _logger.LogTrace("[{typeName}] Disabled.", _typeName);
                }
                catch (Exception ex)
                {
                    _logger.LogError(ex, "Unexpected exception stopping session.");
                    // !!!!!! Dispose should have been called here !!!!!!!
                    throw;
                }
                finally
                {
                    _singleTraceSessionHandle.Release();
                }

The same should be done for start logic.
