Request for Root Cause Analysis on Failure Count and Top_Failure_Reasons in Adobe Journey Optimizer

I am experiencing an unusually high failure rate in our live journeys executed via Adobe Journey Optimizer over the last 24 hours. Out of a total of 68,429 records processed, approximately 52,000 have failed, which is significantly above acceptable thresholds.

The Top_Failure_Reasons section highlights several error types, but we require a deeper understanding of the root causes behind each of these failures. We have attached a screenshot for your reference that outlines the failure categories.

Screenshot is attached for your reference.
