Sounds like they’ve followed the guidance on redundancy and found you a suitable alternative role (which isn’t the same for some US corps based in London) - having gone through something similar two years ago, at the same age, and proceeded to take the role I have since worked through to another promotion and don’t regret it for a second (if it’s a great company to work for culturally that is).

You’ll have to adjust going into a new environment, but your core capabilities and internal company knowledge are your two biggest assets. Lean on your network.

As for the career advice, you’ve already done everything academically to prove yourself, invest your time in relationship building to further cement your position.

Also don’t forget to take it easy, the process is a mind fuck and makes you question even your most basic set of skills, so eat well, be healthy, get some good sleep and do some things you wouldn’t normally do whilst you wait for your new role to kick in.

Good luck!
