Prisma Studio cannot be started with the packaged CLI (because Client can not be generated)

Bug description

Running prisma studio launches the studio in the browser and then crashes:

Environment variables loaded from .env
Prisma schema loaded from tests/data/schema.prisma
Prisma Studio is up on http://localhost:5555
Unable to get DMMF from Prisma Client:  AggregateError: 
    Error: Generator at /snapshot/node_modules/prisma/prisma-client/generator-build/index.js could not start:

      throw err;
      ^

    at next (/snapshot/node_modules/prisma/build/index.js:17854:25)
    at /snapshot/node_modules/prisma/build/index.js:17875:17

Should be noted that the standalone Prisma Studio app and running with npx prisma studio can both be successfully launched.

How to reproduce

#!/bin/bash

set -eux

git clone https://github.com/RobertCraigie/prisma-client-py
cd prisma-client-py

python3 -m venv .venv

set +x
source .venv/bin/activate
set -x

pip install -U -e .

python -m prisma studio --schema=tests/data/schema.prisma

This will either hang or crash.

Expected behavior

The studio should be launched successfully.

[max-programming]

Thanks a lot @RobertCraigie 😄 !

Just FYI I was stuck while generating the client too and I realized I had to change prisma-client.js to prisma-client.py manually in the schema file.

Sounds related to https://github.com/prisma/prisma/issues/10564 - under the hood Studio also uses a generated Prisma Client, so if generating is not possible, using Prisma Studio is also not possible.
