Loading Levels with Remote Control Web App crashes UE everytime

I’m a newbie to UE but I’m coming with a foundation from Unity (I know, there’s a difference.)

I’m working on a personal project, where I want to remotely control the UE app using a web app interface from my tablet. So far, so good. It’s fairly easy to set up and control a number of actors in run-time; However, trying to load levels (open levels by name) crashes UE every single time.

I have tried opening levels by reference name, but I don’t know what Actor to put inside the World Context Object. If I throw in my level (yes, I know, it’s wrong) CRASH! If I throw anything else, like an Actor with event triggers inside of it, I get a message saying there’s no object found in the WCO.
I don’t know C++, which I understand would probably solve my problem. I’m currently looking for an Engineer for help, but in the meantime, I hope I can get around this crashing with BP and exposing the right parameters and calling the correct function library.

The is the crash log I got recently. Can anyone make heads or tails with this? If the fix is obvious, what should I do? If it’s a bug, what are my go-around options?

Thank you in advance!
