Vertical pink & white lines appear after pixel 5 battery replacement

I followed the guide for battery replacement.

Screen was 100% functional before attempting repair. Battery was successfully replaced. After connecting display, I turned on display for screen test and there is one pink and several white vertical lines running through the display. There is no visible cracks or damage to the display. I have disconnected and reconnected the display several times hoping I just didn't connect it correctly. There is no visible damage to the LCD connector. Is there something I could have done wrong to cause this?

The only thing I think I may have done is when removing the old glue from display, I left the tempered glass screen protector on causing a small lip around the outside of the display. Could I have pushed down to hard and cracked the display trying to remove the old glue? As I said before, I don't see any damage to the LCD.
