On the ledge to the right of the big carved doors is the switch that opens them. Once you use the switch, the doors will stay open for about 22 seconds. No worries. You've got this.
Climb up and pull the switch.
The camera shifts to show the doors opening. Briefly press Look to get Lara's perspective back.
Hop back once.
Turn about 90 degrees to the left and hop back once more.
Now take a running jump...
...to land on the low platform between the switch and the doors. Immediately take a standing jump (Jump + Forward/Up with no run-up or grab) to land on the ledge in front of the doors.
Run through before they close. Even if you flub the jumps, you should still have a few extra seconds to reach the doors. If you don't make it the first time, climb back up to the switch and try again.
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. May I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
