STM32L56QE UFBGA 132 -- USB partly disabled due to conflict

Using STM32CubeMX have configured the USB FS device, Debug with 5-pin interface and the SDMMC as an 8-pin interface to drive an eMMC component. The tool is flagging the USB device with a yellow triangle and when you hover on it, the message states partly disabled due to conflict with Debug and SDMMC peripherals. I've checked the IO pins, NVIC, and clocks but do not see any conflicts. Any ideas? Is this a bug because the check applies to parts with lower pin counts and not the UFBGA132?

It's just letting you know that some feature can't be enabled. It's not saying there is a current problem. The warning can be ignored.
