4 long, 5 short is [url=https://www.raspberrypi.com/documentati ... lash-codes]Fatal Firmware Error[/code].
I'd suggest trying to reinstall the bootloader. Use Raspberry Pi Imager to write an SD card by selecting "Misc utility images" for the Operating System, then "Bootloader (Pi 5 family)" and "SD Card Boot".
Use that card to boot your Pi once. You should see an all green screen when it is complete. Then turn your Pi off and try booting off your original card.
The other thing to try is if you have a suitable cable to connect to the UART connector on the Pi (Raspberry Pi Debug Probe works), then you may be able to see some messages.
Otherwise, return it as faulty as it possibly has a hardware fault.
