2012 KX 450 locks up

Was riding in second gear and the back wheel locked up. It still starts fine and runs fine but neutral, first, second, and third are locked up. I can feel the bike click into neutral but the back wheel is still locked up. dumping clutch on limiter in 1st, 2nd, or 3rd just kills the bike. 4th and 5th work, bike will move if slipping the clutch but once the clutch lever is let all the way out the bike locks up and dies. Any ideas?

Bent or broken shift fork or shaft holding forks     Split cases

But it shifts just fine which is weird. I almost think it’s clutch related.

Obviously something is broken in the clutch or more likely trans.  And you’re likely doing a bunch more damage by holding it wfo and dumping the clutch. Blink
