Device crashes / reboots almost immediately

[unixb0y]

I've been playing around with the blinky example, and even reducing its complexity (i.e. just increasing and printing a number) and it crashes consistently after like 1 second.
It starts counting (without delay up to ~300; with delay of 100ms it gets up to the number 4), then I get the "ESP-ROM:esp32c3-api1-20210207" line and the other stuff you see when it reboots.

Is this a known issue?
