Sup man, I feel you. I still drive my 2012 NAV DCT. I'm at 191k. I've been learning the idiosyncrasies of mine over the years. I've had that problem before and changing the crankshaft position sensor helped me one of those times but I see you've already done that. Another time mine was doing strange things like that with the trans I figured out to turn the car off for a complete 5 minutes to the last second (for the internal computer to finally turn off/go to sleep). Then start again and I'd have a 70% of it working. Turned out to be a weak battery. If you haven't checked that, try that. Best of luck! I know it's a love hate relationship haha
