You appear to have a HP 15-ac047tu Notebook PC which originally came with Windows 8.1 64-bit.
Is that correct?

If you completely shut down that notebook, then wait 30 - 60 seconds, then press the power button, does it start up okay?

See if THIS support article is of any help to you.

Also looking at the build #, I see this is 1709.
Support for that ended in April 2019. I suspect you haven't received patches for the last 7 months of this year.

You are going to have to install 1809 or newer.
