"ReferenceError: PThread is not defined" in Chromebooks

[slim]

Description
Hello, our users have been encountering this error when they try to use the web SDK on their Chromebook.

Unfortunately, I cannot test this myself as I do not have access to a Chromebook.

I’d be happy to know if there are any workarounds you can suggest, or if this is already known and a fix is on the way.

Browser Console Error
ReferenceError: PThread is not defined

Which Web Meeting SDK version?
2.13.0, client view

const { ZoomMtg } = window;
ZoomMtg.setZoomJSLib('https://source.zoom.us/2.13.0/lib',  '/av');
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

const zoomError = (message, { method, status, errorCode, errorMessage }) => {
    const error = Object.assign(new Error(message), {
        data: {
            method,
            status,
            errorCode,
            errorMessage,
        },
    });
    console.error(error);
    Sentry.captureException(error);
};

const initZoom = (zoomData) => {
    ZoomMtg.init({
        ...meetingConfiguration,
        debug: false,
        leaveUrl: window.zoomLeaveUrl,
        success() {
            ZoomMtg.join({
                meetingNumber: zoomData.meetingNumber,
                passWord: zoomData.password,
                sdkKey: zoomData.sdkKey,
                signature: zoomData.signature,
                userName: zoomData.userName,
                zak: zoomData.zak,
                error: zoomError.bind(null, 'join error'),
            });
        },
        error: zoomError.bind(null, 'init error'),
    });
};

getZoomData().then(
    (response) => {
        initZoom(response.data);
    },
    (reason) => {
        Sentry.captureException(reason);
    },
);
