Run Explorer of Central UI does not show run history due to 'Null value was assigned to a property'

In OO 2020.08 environment, the Run Explorer tab in the Run Management workspace of Central UI failed to show all run history after it was upgraded from 10.80. All the run history used to be shown there before the upgrade. In addition, new run history of flow executions after the upgrade were not visible too.

When the problematic behavior was observed, there was the following ERROR message recorded in server.log of Central:
