LineAge OS shitbricked my phone

I wanted to flash an open source android to not be tracked by google but now the phone won't even boot!!
All I have is a picture of a dead robot and some error message. What can I do?

I managed to unlock it somehow.
LineageOS is better than the original android which was so frustrating that I had gave up using the phone altogether.
I had to install opengapps otherwise tinder doesn't work.
