The stewards are going to investigate Alexander Albon's car from Red Bull Racing. This was announced by the technical committee of the FIA during the Hungarian GP. The grid box of the British Thai would have been blown dry before the start at the Hungaroring.
Normally some blowers are used to cool the engine, but Red Bull would also have used them to create more grip for Albon at the start. The starting spots were still wet when the race started at 15:10.
