[SOLVED] OH3 Issue - "Model" Page endless loading - Maximum call stack size exceeded in app.js

Very new to OH and this forum so please forgive any protocol and etiquette faux pas.

I’m running 3.0.1 on a Mac with Big Sur 11.2.3.

Everything was working fine until I decided to install the scripting libraries and that is when the Pages page got stuck in a loading state. Other things, including the sitemap that allows me to perform actions like turning lights on/off are still working.

There was some output in Terminal but I logged out, cleared the cache, and restarted and there is no output now.

The browser console is showing this:
