No, you legally should NOT move until the flashers stop and if there is a stop sign on the bus that it has been retracted. It doesn't matter if a bus driver flags you to go... or signals you to go.

When a red X is indicated over a driving lane, a driver must not use that lane. The red X signals that the lane is closed to traffic, typically due to construction, an accident, or other hazards. Drivers should safely change lanes to avoid the restricted area and follow any posted signs or signals. Ignoring the red X can lead to fines or accidents.
