Two thoughts, based on your log:

It looks like your ORPort is 9002, and also your ServerTransportListenAddr
is trying to use 9002? That could result in weirdness.

Something weird happened here -- it's like the process went to sleep
for 31 hours. This is the sort of thing that happens when you close your
laptop and then open it 31 hours later.

There are not many Windows relays (or bridges), so it could be all sorts
of things -- a libevent bug? A thing that Microsoft chose to implement in
a surprising way that's different from every other platform? An antivirus
app that tried to hook the Tor process and ended up wedging it for 31
hours? A clock that jumped backwards by 31 hours?

I wonder if it's https://trac.torproject.org/26360
