use the flash utility to do a chip erase, reload code - do not lock

C8051F321 - flash is being corrupted
As far as i know the external capacitor on RSTn may limit the C2 speed GET RID OF IT in the Cygnal days some .... 'solved' noise by putting a cap on !RST and that morphed into an urban legend that the cap was beneficiial BULL.... |

The Crossbar use
the one thing you can not change with the crossbar is the sequence of devices.
I recall, in the old Cygnal days asking and was told that they tried a :fully universal" crossbar and it took 3 times more space on the die than the processor |

1) do you have a pullup on !RST ? 2) do you have decoupling no more than 5mm from Vdd? |

Sensirion SHT7X Protocol Issue With C8051F320 Digital Input Line
I see one issue
the delay routine is in C and thus the dalay time is unknown
use a timer or make (maybe the smallest ever) assembler module |

The first page of the faulty MCU is erased(EFM8LB11F64E )
also, although possibly not related you are missing the pullup on !RST
