Error upgrading from V2
What I am trying to do:
- Upgrading from V2
- Followed the steps on https://filamentphp.com/docs/3.x/panels/upgrade-guide
- Searched a ton but no one faced a similar error
- Followed the first-aid
- I have basically a blank page with livewire/alpine errors.

Solution
Basically two things:
- One browser extension messing things up (found out by opening on an anonymous tab)
- Had the APP_URL on the .env pointing to the prod website instead of localhost (as now filament publish js/css files to the public folder, they couldn't be reached)
