I had the same problem and reached out to Oculus support to fix it.
For me, the fix was that I had two video cards. The Oculus was plugged into one, and the monitor was plugged into the other. Moving both to the same video card and rebooting fixed my problem.
This configuration wasn't an issue under the older version, but something in the Better Together update didn't like it.
FYI, I also opened Minecraft directly from Windows, on the desktop first.
