getting to wembley stadium from norwich today?

hi all! so as some are probably aware, with the fire at stratford the trains seem to be quite unreliable today. normally i’d drive to colchester from norwich and then get the train into Liverpool street station, and tube to wembley from there, but with the current situation i’m worried about getting stuck, as i faced this issue last night and don’t want to be in the same situation again.

does anyone have any advice for the best way to get to wembley regarding this? are there any other stations which would be good to drive to from norwich and run till quite late? if i could stay for the whole concert at wembley tonight that would be ideal! i know in a normal timetable, the last train from liverpool street to norwich is 11:30, so if i could find a train that could get me somewhere where i could park my car later than that, it would be amazing!!
