What was the highest rated classical game that was lost on time?

Question

Recently, I came across a game Vishwanathan Anand vs Veselin Topalov from Norway Chess 2022. In the second round, Anand who was playing with the black pieces won on time against Topalov as his clock ran out. The position was equal according to the engine.

Is this the highest-rated classical game that was lost on time? Or is there any other game much higher rated?

The ratings were: Topalov (2730) vs Anand (2751)

NOTE: By highest rated, I mean according to FIDE classical ratings and the sum of the ratings of the players. In this example, it is 2730 + 2751 = 5481

Answer 1

Not sure if this is the all-time highest-rated classical game ever lost on time but Magnus Carlsen's game against Veselin Topalov from Round 1 of Norway Chess 2015 was lost on time.

Yes, one more loss on time from Norway Chess itself! This time Veselin Topalov got the win :).

Carlsen was rated 2876 and Topalov was 2798 making it 2876+2798 = 5674. Here's that game:
