Arianespace published this statement on Tuesday morning:

The Soyuz launcher’s automatic sequence for Flight VS23 was interrupted during final countdown operations at 1 hour 25 minutes prior to liftoff on 17 December. As this mission has a launch window with a fixed, exact moment of liftoff, Flight VS23 was postponed. The Soyuz launcher and its satellite payloads – the COSMO-SkyMed Second Generation, CHEOPS, OPS-SAT, EyeSat, ANGELS satellites – were placed in a fully safe standby mode.

The new target launch date will be announced as soon as possible.
