Instead of using ganache using an alternate of that

Run "yarn hardhat node" then there you will find an RPC URL link copy that and paste in your script also copy private key from one of the accounts displayed there

[ybhumi]

yes thank you

[alymurtazamemon]

@ybhumi remove node_modules folder and package-lock.json or yarn.lock file. Then install the dependencies again.

[ybhumi]

thank you so much
