Fastboot does not see device, but fastbootd does

My device: Tecno Camon 19 (cl6n) I need to unlock bootloader, adb see my phone correctly, fastbootd too. But when I do adb reboot bootloader neither the phone nor the PC can see each other. Phone says that after 60 seconds without action, the phone will reboot, and on the PC

devices

gives an empty line, if you try to use any fastboot command, the text "Waiting for any device" will appear. I installed usb drivers and vc reddists, so i dont know why its not working.
