Need advice - Generator Control Module / DC/DC Converter

2013 Prius with almost 190k miles. A few weeks ago, the car kicked hard while I was driving 5mph, then every light on the dash came on, including the “Check Hybrid System” light.

Got a code reader and got the following codes:

P0A94 - DC / DC Converter

P0A1A - Generator control module

C1310 - Speed wheel RF comparison failure

C1241 - Low battery positive voltage

C1310 - Unknown issue/Abs

The repair estimate the code reader gave was astronomical, and my family member said they think they may be able to repair it if I can buy the correct parts.

Has anyone seen anything like this before? And would it be worth it to try to replace the GCM before I mess with the DC converter? Any advice or guidance would be incredibly helpful right now.
