Runtime error in browser

Warn when running "gatsby develop"

I am getting this warn and cannot run my gatsby site because of it. No idea what caused this warn but I've tried everything and cannot fix the issue. I ran "gatsby clean", recloned repo and still no luck. I was however able to run the code no problem from another computer. Any suggestions would greatly be appreciated. Thanks in advance!

Error in function RouteHandler in ./.cache/root.js:21 Cannot read properties of undefined (reading 'Provider')
