The 401k isn’t meant to be cashed out before you turn 62 or something. Don’t do it. You’ll incur heavy fees.

First and foremost, this is not any financial advice/legal advice, just my opinions.

With that said, if you find yourself in the position needing the money, make sure to take care of yourself. As far as getting the stocks, you would need to sell them before cashing out/withdrawing to your personal bank account. In theory, its easy.

Where you may be caught is taxes. A 401K is designed to put pre-tax money in to lower your taxable income for the current year. Additionally, assuming you are not of retirement age, you will also pay a penalty for early withdrawal. So come tax time, you would have to pay taxes on the price of the stocks you sold and a fee.

This is what I'm familiar with when it comes to 401k's in general.

I personally don't know too much about the Starbucks stocks or the starbucks 401k in particular because the fees are too high (for my liking) in comparison to choosing to do a ROTH IRA (just my personal choice).

For SBUX particular things, you should talk to your SM, DM, Corporate, and/or Fidelity and they should tell you SBUX specifics.

A good community to ask about withdrawing from your 401k would be r/FinancialPlanning or r/personalfinance just in general, they should be more helpful.

Hope this helps a bit
