I have seen log messages like this, so maybe the problem also might be related to the cables used.
[ 1595.155477] ucsi_acpi USBC000:00: unknown error 0
[ 1595.155496] ucsi_acpi USBC000:00: GET_CABLE_PROPERTY failed (-5)

I’m only seeing those when I have the USB-A extension cards inserted (as reported here). Are you getting them with just USB-C?
