This is normal, especially when cold.
The clutch drags, period.
Most dirtbike clutchs drag, but the WR line drags even more.
You start in neutral, then 'blip' the throttle before putting it in gear, and then it won't stall.
If you have removed all but 1/8" of free play from the cable, and the motor is hot, it will typically start in gear, but not well, and not advised, as it will put undo wear on the starter motor and starter clutch.
You can purchase a higher pull-ratio lever to help it to disengage farther, but the clutch pull with then be harder.

Didn't have any such problems on my 2014. Not that it probably matters but I don't use synthetic. I use yamalube 10w40 or some equivalent and change it often.

hi this is not an uncommon problem, I have had sticking clutch plates over the years in various bikes.
is an easy fix get you bike warmed up take it for a ride, if it stalls when you put in gear push it a little jump on and knock into first.
get the revs up a little and if clutch wont disengage start applying front brake while you keep revs up at same time working clutch lever in and out
when it disengages (and it will) slip it a little like your ridding the clutch this will help burn the crap of your plates.
then while its still warm drain your oil and replace with something like Yamalube lube semi synthetic
Yamaha designed yamalube for these bikes and a lot of people make the mistake of what's the most expensive oil I can run in my bike.
yes top grade oil has additives in it to protect you engine but a lot are not designed
for high performance wet clutches
if you change oil say every 10 hours (and that's way b4 needed but that's what I do) I bet you don't have a prolbame
