Hi, every second Sunday in December there is the yearly timetable change in Europe. So interrail.eu/eurail.com can at the moment sell only to the 10 dec 2022. 

On the other hand, Eurostar has already opened their bookings for timetable 2023 (11 dec 2022 and after). Online this is at the moment only possible via b-europe (+4€/booking). 

Keep in mind that Eurostar trains has only a quota for pass users, if this quota is full only full fare tickets are available. 

If you must have a Eurostar date after that date Eurostar will sell you a ticket for many trains for a reasonable price

Thank you Angelo, so can i book using my global pass on b-europe ?

Yes but only via this link https://www.b-europe.com/EN/Kopen/Pass#TravelWish and not on the b-europe homepage. And you need a paper pass cover number. If you have a mobile pass you can get a cover number here:
