I’m sure some people here do understand the crash logs, but I do not. You can email support and attach the crash logs and see what they say.
The fact that BI mainly crashes at night is a clue. Something is changing at night that’s causing it to crash, wether it’s some program that auto runs, a failed windows update that keeps trying to install, or something else. Look at your computers active hours and see if the crashing corresponds with it.
At this point a clean install of windows would probably be the easiest solution. However, I still don’t understand why you allow the computer to sleep. Doing so Will prevent BI from recording an incident, and I’m sure it’s not good for the database.
