BEAS ADD ON DOES NOT START

GOOD MORNING WE HAVE THE PROBLEM THAT THE BEAS ADD ON DOES NOT START FOR ANY USER, IF IT WORKS IN A SAP B1 ENVIRONMENT BUT THE ADD ON DOES NOT START, WE MUST RESTART THE SERVER FOR IT TO WORK AGAIN, WE DO NOT KNOW THE CAUSES THAT CAUSE THIS, THERE WILL BE SOME SUGGESTION
THANK YOU
