How likely is it I will be able to cash out my USDC from Coinbase tomorrow ?

I am absolutely beside myself with worry. I have about $20k in USDC on my Coinbase and there is a family emergency in progress and long story short, I REALLY need that money. I feel physically sick thinking about what might happen next.

I wasn't paying attention to the news at all and just noticed what was up an hour ago when I tried to sell my USDC to cash out.

Is this going to be another Luna episode or am I over reacting? This literally could not have come at a worse time as far as I'm concerned.

Also, what time do the markets open tomorrow? I want to just jump in and take this out straight away.

Thank you for any advice.
