Install the latest version 7.0.3 of ganache instead ganache-cli

npm install --save-dev ganache

in code just use

const ganache = require('ganache');
const web3 = new Web3(ganache.provider());

in my case, reinstalling ganache-cli fixed it for me.

Found out this to be a problem with node v14.x and ganache-cli v6.12.2 (ganache-core: 2.13.2).

Installing node v13.9.0 solved the issue for me.
