Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

Hi Darren,

I'm trying to load this firmware on my Tickertape I've got from you (Kickstarter backer #91).

At first I was running the original firmware that came with the device but unfortunately I wasn't able to configure (or figure out) the brightness setting.

I've now loaded this firmware on the Tickertape device with the VSCode Platform.io extension. The device has remembered the old wifi settings so it doesn't start the hotspot for configuration in the browser. Blocking the device in my router got it to start the hotspot for configuring it using the wifi portal page.

However, the device crashes as soon as I try to connect to the wifi page:

Do you know how to remedy this so I can configure the device using the wifi portal page (or maybe in a different way) ?

Thanks!
