Roof door won't open on Follow Freeman

In the "Follow Freeman" chapter, after Barney opens the rooftop stairwell and after passing a turret, the stairs take you to a nonfunctioning door. The map does not advance to the next section, and there appears to be a rendering glitch as the stairwell becomes invisible. This is on a Windows 10 PC running Oculus Quest headset on SteamVR. Rebooting all hardware and upgrading NVidia drivers did not fix the problem
