Could you make a post on the AnswerHub (https://answers.unrealengine.com/) as well. Doing so will make it easier to assign a member of our support staff to investigate and respond to the problem you’re having. Once you’ve created the post on AnswerHub you can add a link to it here for reference. Please be sure to include as much information as possible including which engine version you’re working in and what steps were taken that led to the error message.
