How do I reset this pc?

With Windows, this is a massive red flag and usually points to a tampered or damaged OS installation, but it's generally caused by tampering. Since you are erasing it anyway, the only way to be sure with that kind of issue is to erase the PC and reload Windows from a USB drive. Backup your files first of course, but the only way to be sure is a wipe and reload.

Write the OS image to a USB drive and delete all of the partitions - do not keep anything given the high risk of tampering.

What I have done with machines that show this with an SSD is I will wipe the PC out with a tool that does an NVMe Secure Erase or ATA Secure Erase to be sure the drive. The exception is spinning rust - 3+ hours is excessive. I personally use Parted Magic.
