Error when using WebGL in Android build

[MoJaeCheol]

It works well when you use the external URL of the Android build float (the https address with the WebGL build file) as a web view. However Repeat web view open close approximately 5 times and enter an
error: Cannot read undefined properties (read 'GLCTx') on object. deleteContext(/URL) error occurs.

webViewObject.ClearCache(true);
webViewObject.ClearCookies();
I've tried various things like this, but it's not working out. Any suggestions?

It seems to be caused by emscripten's bug (cf. emscripten-core/emscripten#22889 ).

Thank you for your answer.

I'm building WebGL in Unity,
I don't define escrypten separately.
The most likely reason why I found it is
emscripten-core/emscripten#14595
I think that's why it's on the link, but it's hard to know how to solve it, so I'm asking for help.

You could try several older versions of Unity to emit WebGL content. Older versions might utilize more stable emscripten.
