The stable Android 11 update for the OnePlus Nord started rolling out just over a week ago, but that rollout has now been paused. It turns out that several bugs have slipped through the three open beta testing stages.
The OnePlus team is working on fixes and once they are done the update process will resume. If you have already installed Android 11 on your Nord, you will receive a separate update with the fixes.

There’s no official list of bugs, but users have complained about various issues after installing the update. There seem to be battery troubles with increased drain and slow charging. Other reports point to GPS issues, as well as problems with features like Parallel Apps and the App Locker.
