I’m comparatively new to BTC however i’m all in on the ideas behind it. I do know nothing about coding or cryptography, however I like the idea of decentralization and I’m an enormous Austrian Econ nerd.
I had about 0.045 BTC in Coinbase Pockets, and transferred about 1/3 of it to my Bitcoin Core node on my macbook for the sake of getting it out of a centralized alternate. I’ve been operating the Bitcoin Core software program for a few 12 months and a half now, however by no means used it as a pockets till every week in the past.
On 9/22/24, at 1500EST, the Core app stopped synchronizing with the community. I did some analysis as to why however didn’t make any adjustments. This morning, 9/24/24, I made a decision the most effective factor to do could be to extend the RAM allotment for the Bitcoin Core app within the preferences. A number of individuals on numerous boards mentioned this helped them when the Core app stalled in synching with the blockchain.
A dialogue field popped up and mentioned I wanted to restart the app for the change to provoke. I did so, after which every thing went to hell.
As quickly as I reopened the Bitcoin Core app, the next dialogue field popped up 
[You need to rebuild the database using – reindex to go back to unpruned mode. This will redownload the entire blockchain.
Do you want to rebuild the block database now?]
After I chosen {OK}, this dialogue popped up subsequent. 
[Error: Error opening block database].
After I choose {OK} on the second dialogue field, the app crashes.
As I mentioned, I’m comparatively new to Bitcoin, and I’ve gone down the ideas rabbit gap for in all probability over a thousand hours, learn Bitcoin Commonplace, Layered Cash, Dom Frisby’s Books, listened to each episode of Breedlove’s What Is Cash present, and so forth. However I don’t actually have experience on the usage of the app, or of command prompts or coding in anyway. I additionally, like an entire fkn fool, didn’t write down my non-public key, as I didn’t even know how one can extract it from the Core app, and I hadn’t devoted that a lot time to figuring it out as a result of I actually didn’t assume I would want it but. Lesson discovered.
Any knowledge concerning how one can get the app to work once more, how one can replace it, how one can drive it to begin reindexing instantly on opening, how one can discover my non-public key from the db recordsdata, and so forth could be EXTREMELY welcome. Like I mentioned, I solely have about 0.016 BTC on this pockets, which isn’t a loopy quantity, but it surely’s not nothing (~$1000 as of 9/24/24) so yeah, please and thanks to anybody and everybody right here who would possibly have the ability to throw me a rope.
