Before you do anything at all, please make sure that you have backed up everything to a safe place. You can either use iCloud, iTunes, or Finder. As long as there's a complete backup of your iPhone, you're good to go. Also, take as much time as possible to back up your device - it is extremely important.

Next up, disable Find My on your iPhone. Launch the Settings app, tap on your Apple ID at the top, then tap on Find My and then go to Find My iPhone. Disable the feature and enter your Apple ID password when required.

Download the right iOS 15.6.1 IPSW file for your iPhone and save it to your desktop:

At this point, assuming you've done everything correctly, connect your iPhone to your PC or Mac using a Lightning cable. Launch Finder or iTunes once the device has been connected and detected by your computer.

Select your device from the left-hand corner to reveal more options. You will now see a Restore iPhone button in the center, simply click on it while holding down the left Shift (Windows) or Option (Mac) key. Select the iOS 15.6.1 IPSW file you saved to your desktop.

Once the file has been selected and opened, Finder / iTunes will verify the contents and restore it onto your device. Remember one thing - iOS 15.6.1 is being signed by Apple at the time of writing. Once the signing window is closed, you won't be able to downgrade later.
