When resetting the laptop it sticks at 50%, what to do?

I pressed the button this morning at around 11 a.m. To reset the laptop.

Before someone asks why: The laptop is littered with all sorts of things and there were also some things that no longer worked, which is why the last option was to reset it.

I did it, at the beginning it went pretty well, but suddenly it got stuck at 50%. At first I didn't think anything about it and waited. A good 1h 30 minutes have now passed and it is still at 50%.

You hear and "feel" that he is working, but the number does not increase any further.

It's an Asus wind. 10.

To my question:

What should I do?

Keep waiting. As long as he does what there's hope. And it is so that with certain% numbers it feels like ages, even hours, until it goes on.
