Unable to play snapshot

I do understand that snapshots are updates in progress, therefore there will be bugs, this bug is related to Snapshot 17w43a, but none the less, I can't get on. Once the game downloaded the snapshot, when I press play, the game pulls up for not even a second, then it will say the game has crashed. But if I try to view the crash report, nothing will pull up, hope you could fix this soon! Thank you for taking your time to read what problem I've had, and I would really apreciate it if you commented when you have fixed this issue, thank you!
