Attiny13 Failed to Upload New Program

Using UsbAsp I burned hex file to make led candle project.
Link is here:candle/main.hex at master · knik0/candle · GitHub

Attiny13 working fine and led start blinking as a candle but now UsbAsp failed to upload any new program to the same Attiny13. I checked with new Atttiny13 and works fine to check the issue with UsbAsb but no issue to program new Attiny13. But why old Attiny13 programmed with hex fie stop uploading new program and stuck with candle hex file. Please suggest me any solution.

Thank You
