React-native-debugger: `Cannot read property 'prototype' of null` after upgrade to RN 0.63.2

Hello! I had previously have issues with network requests. Requests itself hadn't been visible, or request response was blank.

Reading few issues here I've added to root my index.js:

global.XMLHttpRequest = global.originalXMLHttpRequest || global.XMLHttpRequest;
global.FormData = global.originalFormData || global.FormData;

if (window.FETCH_SUPPORT) {
  window.FETCH_SUPPORT.blob = false;
} else {
  global.Blob = global.originalBlob || global.Blob;
  global.FileReader = global.originalFileReader || global.FileReader;
}

GLOBAL.Blob = null;

Everything was working fine till upgrading to React Native 0.63.2. Now Simulator always displays an error: Cannot read property 'prototype' of null. Removing GLOBAL.Blob = null; resolves this issue, but network request info, such as response and params are not visible anymore.

Maybe someone already faced the issue and know how to fix it.
