Full error output:

Other than UART0 being used for the BG95, are there any issues using UART1 or UART2 (or both) to talk to external devices? Do the QWIIC ports have pull-ups on them or could these be used for a UART? I need to talk to one and maybe two serial devices through a MAX3232 for sensor readings.
