Hello, I'm new here, I have a very annoying problem and I want to solve it ... my wallet is Bitcoin Core, last night I rebooted my computer and when it rebooted, when I opened Bitcoin Core, it was in an infinite "Replaying Blocks .... 0% "If anyone can help me thank you very much!
Sounds like you shut down Bitcoin Core uncleanly. My suggestion is to wait and let it do its thing. If you want to make sure the application hasn't frozen, check whether new entries are being added to the debug log. Going forward always allow Bitcoin Core to shut down gracefully, never force it.
