I don't know why he wants to roll back to 1236268, which will cause me to lose a lot of data

Do you have any unclean shutdown? Geth will lose the in-memory states if unclean shutdown occurs, an additional state recovery procedure will be scheduled if so in the next startup.

Yes, my server suddenly stopped, and when I found it and started up again, the above problem occurred. Is there any way to solve it?

Not really, it rolls back the chain and goes from there. If there is another node in the network, it will sync back up again.
Not much we can do about it, sorry!
