There is no way to update Dynamo for Revit, only to update Revit.
It’s a near 100% certainty that you’ve got an invalid version of Archi-Lab (review this link). Your version needs to end with the same as your Revit year… which brings me to my last point.
You’re using Revit 2021. it has been over 5 years since that was released, and is an entire version and a quarter outside of the support window. You need to update your Revit project to a supported build for security reasons alone, never mind trying to build automations.
