what can i do to fix it

First, may I ask what exactly do you mean by upgraded to netrunner rolling?

I can’t tell from the picture what’s going on exactly. It looks like it was not shut down properly (recovering journal), or you may have had an incomplete or failed update. The last line is the network (Lan) driver loading, I can’t tell what is loading after.

Boot without quiet splash in the kernel command to see what’s happening after the Lan driver loads.

This may also be useful in diagnosing why your system is not booting:
