Pixel 2 stuck on TWRP splash after flashing

Hello, I’ve been googling around and I think i have tried everything I could on the forums. I was following the instructions on unlocking the BL and that went off without a hitch. However when I installed the taimen img file and went to start TWRP. I got frozen on the splash screen.

No security is set up, swipe has been set to the default.
I have only used the files located in the ‘How to’ section here on HighOnAndroid.

Any thoughts on how i messed this up?
