AWS Redshift query editor v2 - Run button is inactive for all saved queries

Hi,

All of a sudden, I cannot run any saved query in AWS Redshift query editor v2 as Run button became inactive for unknown reasons. If i create a new query, it works fine until i save it. What is happening and how to fix it? Closing and re-opening browser and tab did not help. I use MS Edge, latest version, and do not want to switch or try anything else.
