Regarding this:
Nahimic is typically bundled with motherboard software. You’ll need to find the make of your motherboard (MSI / Gigabyte / Etc) and uninstall any motherboard software from your control panel, then restart it. It should prevent the Nahimic software from starting. If you use any of the software, you can try reinstalling it to your computer after you verify it’s fixed. If the problem comes back after, you’ll need to reach out to your motherboard’s support team for configuration advice for how to disable it.
