You've accidentally set "Pause on Exceptions" to all/uncaught exceptions.
Go to the "Sources" tab. At the top right hand side, toggle the button that looks like the pause symbol surrounded by a hexagon (button on the far right) until the color of the circle turns black to turn it off.
If you were unfamiliar with the tools, it was likely that at some point while in the debugger you toggled a setting that was causing the debugger to stop the application.
For anyone that's searching why their chrome debugger is automatically jumping to sources tab on every page load, event though all of the breakpoints/pauses/etc have been disabled.
For me it was the "breakOnLoad": true line in VS Code launch.json config.
