I confirm you that M5Stack-Fire with UiFlow v1.14.0 shows the same error at boot:

Yes, there is only one specific UiFlow firmware for the M5Stack-Fire.
Problem is only related to latest UiFlow v1.14.0, previous versions (1.13.9 and below) work right.

M5Stack-Fire (SKU: K007) doesn't boot (black screen) after burning UIFlow v1.14.0 with M5Burner.

Hardware related problems can be discarded because previous version (UIFlow v1.13.9) works right in the same device.

Best regards.
