WARN: Execution Engine for Frame is not found!

To my SysML and Cameo Simulation Toolkit Colleagues:

Recently I was working with a model which kicks off a UI from Cameo Enterprise Architect (CEA 2021x). This simulation and UI experience was working as expected in May 2024, but when I went to execute the simulation today (12 June 2024) I received the error in the subject line. Has anyone in the community experienced this error? @IH  not sure if you're the right group to tag, but if you could help or point me to the right folks, I would greatly appreciate it.

TIA...Cameo Simulation ToolkitCameo Enterprise Architect 2021x
