I'm experiencing strange behaviour with REPL in paste mode. After an arbitrary period of time, pasting anything while in REPL paste mode will crash the board and bring it back up in safe mode.
While in safe mode, paste mode works without an issue. Resetting it back to normal mode, paste mode will crash it to safe mode every single time. Typing in 4 characters will cause a crash. The crash will occur while typing in the 4. character. CTRL-C or CTRL-D will cause a crash immediately.
Cycling power and removing libs and scripts from internal storage doesn't solve the issue. I have to, either reflash the board with CP firmware, use flash_erase_express.ino.metro_m0.uf2 or run storage.erase_filesystem() from REPL.
I first suspected that the filesystem got corrupted during many resets. I've reflashed the board and made sure USB was ejected cleanly. Same issue occurred after two hours of running the script.

Board: Metro M0 Express
Libs: adafruit_dotstar
Script I was running as code.py
import time
import random
import board
import adafruit_dotstar as dotstar
dots = dotstar.DotStar(board.SCK, board.MOSI, 50, brightness=0.01, auto_write=False)

n_dots = len(dots)
try:
while True:
#fill each dot with a random color
for dot in range(n_dots):
dots[dot] = (random_color(), random_color(), random_color())
# show all dots in strip
dots.show()
time.sleep(.25)
except KeyboardInterrupt:
dots.fill((0, 0, 0))
dots.show()
