Сan't sync last 64-100 block

[ArtemkaMakarenko]

Ethereum node stuck, and can't sync last 64-100 block.
currentBlock cannot catch up and be equal to highestBlock
I studied these articles but none of the above solved my problem.

It's not stuck, it needs to sync the state now.
An Ethereum node has all old blocks and the current state of all smart contracts/balances. During sync we need to download all old blocks and the current state. Your node has synced the old blocks, but it has not synced the state yet.
You can see that the knownStates which are the states that you need to download differ from the pulledStates which are the states that you already downloaded. The pulledStates are increasing between subsequent calls to eth.syncing which indicates that you node is downloading the state. So your not stuck, you just need to download more. You can run --syncmode=snap instead of fast sync which improves the state download drastically.
