Not able to format kali linux pendrive

I have made bootable pendrive of Kali Linux. I was using it regularly in my laptop. My laptop has windows 10 but for using kali linux I am using the pendrive. Yesterday, I tried to install xampp in the kali linux then I got some permission error. After that kali linux is not booting from pendrive. Now I am trying to format the pendrive in windows 10. But I am not able to format it and getting the message as "Windows was unable to complete the format". So can anyone please tell me how I can format the pendrive so I can reinstall the Kali linux.
