[Web] Stuck at "Attempting to connect to browser instance" #49103
Description
My web project compiles without error, but on launch, the browser opens with a blank page and Android Studio shows "Attempting to connect to browser instance" indefinitely.
Just ran Flutter upgrade now.
The console in the browser shows
Uncaught TypeError: Cannot read property 'core' of undefined
