You're very welcome.
Your notebook is a relatively new model, so if it is still under warranty, you should contact HP technical support and submit a support case under the warranty.
99% of the time, that error code means the hard drive has failed.
Since your notebook has an eMMC drive, the entire motherboard has to be replaced to make repairs.
You can try to reinstall W10 as follows, but if it doesn't work, then the notebook's motherboard will have to be replaced.
To reinstall W10...Use the Media Creation Tool. Make the 64 bit installation media.

You can make a W10 USB flash drive installer using an 8 GB flash drive using another Windows PC, since your PC is not working.
If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option, and W10 will install and automatically activate once you are connected to the internet.
Here are the steps to create the W10 USB flash drive installer...
- Select Download tool now, and select Run.
- If you agree to the license terms, select Accept.
- On the What do you want to do? page, select Create installation media for another PC, and then select Next.
Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10. You want 64 bit.
- Select which media you want to use:
- USB flash drive. Plug in a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.
Then you can install the drivers and available software from your notebook's support page.
