Thank you for reply😊

Due to the lockdown situation here by pandemic covid 19 , I am unable to reach out the service center.
Can you suggest some methods to fix this error that can be done via cmd or by
any other applications .

Simple, long-press the power button to reboot it. If it comes back to fastboot, then go to recovery and wipe your device, that should do.
If you’ve installed a custom recovery, then I assume you do have some idea about flashing and restoring ROMS, you can try flashing a ROM of your choice(if available). Alternatively, you can factory reset from recovery, or you may flash your default boot.img file.
For Details :
Open your ROM Zip folder and copy the boot.img to a place in Desktop.
Connect your Device to your PC via cable
Open CMD, type fastboot devices and hit enter (check if your device is shown)
type: fastboot flash boot and hit the spacebar once, now drag the img file to the CMD window and hit enter.
It will flash the boot.img file which should fix your device.
Also, you can dirty flash your current ROM if the above step fails
