Moving SystemClock_Config Causes Strange Erros

I know this is a vague question, but it's a very strange problem I'm facing. My application (based on STM32G0) is working fine. I used CubeMX to autogenerate all the code, and have been building on top of it. Now I am looking to clean things up a bit...

For ADC input, my input signal is sinusoidal with no DC, that is, it has positive and negative value. Is it possible to convert a negative value without problem?

In the document, the input level is limited by Vref+ and Vref-. But Vref- seems to be tied to GND in general, which implies a negative value cannot be converted without problem.Can Vref- be connected external -5V or -3.3 V for handling a negative val...
