Ah. The STM32HAL needs to know your HSE speed too. So you need

[env:genericSTM32F303CC]
platform = ststm32
board = genericSTM32F303CC
framework = arduino
lib_deps = stm32duino/STM32duino FreeRTOS@^10.3.2
build_flags =
    -fexceptions
    -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
    -D USBCON
;    -D USBD_USE_CDC
	-D HAL_PCD_MODULE_ENABLED
; change from default 8MHz to 32MHz
    -DHSE_VALUE=32000000
