Yeah, the block is correct. Can you try to send coins to a new wallet? Try just few
I tried to send to exchange few of them and it crash at the same moment.
Today it didnt want to sync i just reinstall it and its staking again.
We will see how long it will last.
Don't send to exchange, send to yourself, to a different computer. Just download a new wallet and try to send coins there. If they come, then send them all and you can use that new wallet from then on.
