If You Have the Latest iTunes Backup

Connect your iPhone into computer, open iTunes, and click the iPhone icon when it appears on the top left corner. Select "Summary", click Restore Backup..., and then see if your phone can turn off once the process completes.

You can also back up your iPhone before restoring it, provided that it can respond to taps - you need to tap Allow on your iPhone 8 to let it connect to the computer.

In this way, all the data on your device will be wiped out. And you may try several times to boot into DFU mode, since the steps are a bit difficult.
