The complete error message is shown on Edge is The error was : RuntimeError: Memory index is out of range at Module[dynCall_viiii] (file://../Build/WebGL.framework.js:25538:2). Meanwhile when I tried to run it on Chrome it says : abort("both async and sync fetching of the wasm failed") at jsStackTrace (file://../Build/WebGL.framework.js:724:12) This error shows up only after integrating WebSocketSharp into my project, I've been looking into existing posts on the forum but nothing explain about this. What should I do now?
