Behavior

9.0.2�\Stopping because of CTRL-C
Code done running.

The code receives 3 CTRL-C on startup, making the code unable to run without starting it with Thonny or any other IDE.

Is thonny started when this happens? Does it work ok with 8.2.x? Do you have anything else connected to the Pico W?

Thonny is started, Haven't tried it with 8.2x. It's a barebones Pico W. Only happens on startup, after the issue, when the repl starts CTRL+D or the run button on thonny works fine.

If you don't use Thonny, do you see the same issue?

Stray KeyboardInterrupts sound like Thonny trying to stop a running program.
