Clutch drivetrain issue

[slidesquad240]

I have a s13 ka and I was at a drift event yesterday when I lost my clutch. I did one run car was fine I pulled off the track to get back in line and when I went to move up the car just stalled and my clutch pedal was stuck to the floor. I started the car in gear and it doesn't move forward. Then we tried bleeding the system and ended up popping the piston out of the slave cylinder. I removed the trans today and it seems ok I put it in gear and spun the input shaft there's no weird noises or anything. I'm pretty stumped on this any help would be great
