We experienced an increased rate of errors related to executions that are initiated with a Scheduled Trigger between 10:40 AM and 1:40 PM UTC today (24th of November, 2022). The issue only affected workflows which only allow 1 execution to run at a time. Users who were impacted may see that some of their executions failed with the following message: "Stopping because of a potential risk of two overlapping executions.".
