Hi Harrison,
I'm Paul and I'm here to help you with your concern.
Normally, Reset PC only takes not more than 2 hours but interrupting the process might result in unbootable Windows or other unexpected issues so I will suggest that you give it more time to finish. If it still stuck for more than 8 hours then I suggest that you interrupt it by force restarting the PC.
Let me know how it goes then we will proceed from there.
Thanks.
