I’m asking for solutions and answers. Yeah. I’m aware of how hard it is to get metrics.

You can still compare lines of code and bug rate over the same period of time.

You can, but then "The cake is a lie.", because linecount and bug rate, when concieved as proxies for productivity[1] or quality rarely match up with reality in a way that allows you to make predictions or reason about past outcomes.

You can reason about frequency of particular types bugs, such as null pointers or overflow, or whether those bugs can occur at all.
