I’m getting this error today with no display on the ILI9341 3.2" LCD.
The experiment mode was enabled on MakeCode Arcade BETA.
Here’s the UF2 patch I used.
The patch was created using the hex to UF2 Python conversion script found on Adafruit’s nRF52840 repo.
The display config was modified for the 320x240 ILI9341 LCD.
