AVAX blocked in C-chain

I sent some avax from X-chain to C-chain. An error appeared saying : insufficient funds.
from advanced I tried to import C but it didn’t work. I got the message insufficient funds.
I tried again to send a small amount from X-chain to C-chain and now the error is : outputs not sorted and unique.
I can see that the total amount is stuck in the C-chain.
It could be great if someone can help
