Unity Application build shows just a black screen and some errors, what should I do?

I built my game that I have been working on for quite some time. (6 months) and I made a unity build to test it out and when I run the application, all I get is a black screen with some weird white flashing lights on the screen. I can still hear the audio from the game and when I walk I can still hear the footstep sounds in gameplay but I just cannot see anything going on. I have a few errors that came up, I don't know if that is the issue or not or if it's something else. I haven't seen anyone with this problem before. I am using HDRP 2019.3.6f1 to create this project if that helps. I would appreciate some insight as to what I can do to fix this issue.
