This website recommends about 70psi front and rear. I would not ride with such a drastic F/R difference.
It’s really hard to say “your pressure was too high and therefore you crashed”. Riding 28% higher pressure than recommended should not cause a crash, since this website is a bit “newschool” and recommends lower pressures than people ran in older times. Especially compared to 120psi Gatorskins. Those tires have quite hard rubber.
I’d start at 70/75 and see if you feel anything different. Don’t worry about minimum pressures too much. I don’t think you’re anywhere close to the danger zone. I’ve run 25mm tires at 38psi in a race - but my system weight was also 65lbs less than yours.
At your weight, I would also maybe consider some bigger rubber if you like to charge hard on crappy roads. Bigger rubber lets you get more grip and not pinch flat. 35mm tires are going to be in fashion quite soon.
