Try typing the following on YouTube:
How to hard start LG G8. Read/listen carefully as an option might include ERASING your data.

OR
You could do a factory reset but risk losing all your saved data if it was not backed up somewhere:

Turn off your LG G8 ThinQ. Press and hold the volume down and power buttons at the same time. When the LG logo appears, keep holding the volume down button but release the power button and then press and hold it again. Release both buttons once the “Factory data reset” screen shows up.

the phone may need to reflash so you should take the phone to a mobile service center and have that done or try the lg website for more assistance.

SOURCE: stuck on startup screen

it looks like your software firmware is damaged and your phone will need 'reflashing' this can only be done at a phone shop and should not cost too much
