The Scene "live2d" doesn't work by Uncaught type error.

[hiphophal]

Hello. I cloned this, open scene "live2d" and run at my browser. But it doesn't work(not show charactor. can see UI parts. please see screen shot.).

There is a Uncaught type error.
This is a error message.

/**
assets\Live2dForCocosCreator-master\assets\components\live2d\src\LAppPlatform.ts:80 Uncaught TypeError: Cannot read property '_buffer' of undefined
at eval (eval at (quick_compile.js:238), :124:41)
at utils.js:81
*/

This is my environment.

・OS Windows 10 Home (Version: 1903 / use on Bootcamp)
・Cocos Creator (Version: 2.40)
・Google Chrome (84.0.4147.89（Official Build） （64 bit）)

If my english is not well, sorry. I'm glad if it could work. thank you.

I made it in Cocos Creator (Version: 2.2.1) Maybe something has changed in new version
I will checkout latter.
