Unreal 4.18.3 Swarm Failed to Kick Off

It seems that I have a FileAccess user right issue; however, everything that I am using comes from the web and from folks sharing, freely, their work.
Can anyone explains to me how to find this file, I'd love to NUKE IT OFF my project!
Thank you very much.
I had this same exact problem before a few times. Unfortunately the way i solved this problem is by sorting out all of my actors to different folders then started deleting them one by one. I have such a large project that it took almost two weeks to find. The problem was one radio actor that i downloaded from the web. Evidently the naming on the object was causing it to fail.
Another time i had this issue i had to do the same thing, but since everything was organized it only took a day to fix. The issues this time was i had two objects named the exact same naming convention. The reason it happened was when i was duplicating assets. Evidently it bugged and kept the same name.
I know it can be a long process but trust me. After everything i tried and weeks of trying to troubleshoot the problem organizing and slowly deleting your actor is the best solution.
