Official summary
Some 2021-2023 F-150 vehicles may exhibit a no crank/no start with a battery draw and air conditioning (A/C) clutch engaged at all times. This may be due to an opened diode in the A/C clutch field coil damaging the output driver in the body control module C (BCMC). To correct the condition, follow the Service Procedure to replace the BCMC and A/C clutch field coil assembly.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
