Intel Bluetooth Totally Missing after sleep

Hi, after clean bigsur installation on Gigabyte Z490i ITX / 10700K I've added IntelBluetoothFirmware kexts. At first run everything was great. Bluetooth worked and wifi either. But then my pc went into sleep mode and after bluetooth completely gone. From system report at bluetooth tab I see nothing. Can someone help?
