WPs cannot be restarted after saving a Queue with Calendar Event Exception

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

WPs cannot be started anymore (all WP stop) if a particular Calendar Event is added as Queue Exception.
Somehow, WP calculates a wrong date, ie 2021.04.31 00:00:00 for the OUA_NextCheck value which cannot be saved into the database generating the error "Invalid time format"

Errori in WP traces look like this:
