    The same problem after updating to 2021.2.2 in a project with URP, but after playing with the settings it stopped showing up.
    Try this:
    Project Settings> Quality> Render Pipeline Resource [click to view the asset in the "project" tab and select it from there], after selecting the asset, go to the Inspector> Quality> Anti-Aliasing (MSAA)> and change it to Disable tab. Now play the game (press the play button) and turn it off after initialising (after few secounds). Then you can change the Anti-aliasing (MSAA) back to your choosing (I'm using 4x) and the error is gone - at least it worked for me ...
