There appears to be mislabeling of PINs PC0 and PC1 on the MB1779B schematic pack. found here on sheet 3 of 8. The PC0 and PC1 pins are mislabeled as UART1s but according to the datasheet for STM32WL5MOC they are actually LPUART1 as Alternate AF8.

They are labeled UART1 of the STMOD+ connector. This is correct. The "UART1" here refers to the STMOD+ connector, not the peripheral on the chip.
The same as how other STMOD+ pins are labeled--GPIO4 vs PC13.
