This thing is only happening with IDE, I also updated the STLinkV3 firmware, restarted my PC several times and also changed my cable but I am still getting the error. 
Kindly help.

Hello @athern27 ,

Did you try connecting with STM32CubeProgrammer to erase the chip and recover?

Check the BOOT0 and BOOT1 jumper settings on your board.
