I just had a look at your video, a bit short, but at least it's clearly shows the issue, from the configuration you posted I can identify the issue, so please change the related setting and try again.

You should not disable it, just make sure the number are correct.

This looks like the thermal protection of the printer has been activated. Have you set the correct parameters? THERMAL_PROTECTION_HOTENDS THERMAL_PROTECTION_BED THERMAL_PROTECTION_CHAMBER THERMAL_PROTECTION_COOLER
