Error when running local instance #7

Describe the bug
When trying to run locally using yarn start (or, equivalently, using the ./start.sh script, I get the following error:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/tokenize' is not defined by "exports" in /Users/diders01/projects/pgv_init_test/node_modules/postcss-safe-parser/node_modules/postcss/package.json

I had to downgrade node to version 16 to get it to work. We should probably consider updating since the current LTS is 18.
