Solution: Change the installed version of the svelte package to something other than the existing version. The specific version to be installed doesn't really matter, experiment with some versions and that should solve this error. Here is the npm command to install a different version:

npm install svelte@3.3.9
// or
npm install svelte@3.3.2
