I don't think you quite get how Ofcom works.

Ofcom received a complaint in Feb 2020[1] which it investigated -- taking a year to reach this conclusion is not 'sudden'.

The request to transfer the licence to another entity didn't supply all the required information for the transfer[2].

Ofcom operates with a bias against meddling[3] -- you've got to try quite hard to get them riled but not complying with broadcasting law is definitiely one way to do it.
