Google Picker [gapi.load('picker')] load throws previously unthrown error

We load the Google API and picker in a similar way to the example provided on their documentation

We include the script in our html like:

<script id="scripty" type="text/javascript" src=""></script>

And then in our js:

$('#scripty').load(function () {
  window.gapi && gapi.load('picker', { callback: () => {
    console.log('loaded picker');
    // excluded logic here.

We've had this bit of code live and in production for 6+ months now, but only recently (past few days) it has started throwing the following error on console:

api.js:11 Uncaught TypeError: _.Rp is not a function
    at X (
    at qa (
    at W (
    at b (
    at Array.Y.r.(anonymous function) (
    at Object.Y.x.(anonymous function) [as loaded_1] (

And the global google ( variable no longer loads into place. We've checked out extremely old code to ensure it's nothing that we've changed, and can confirm something changed with the Google API. Has anybody run into this issue?
