   Can you paste the end of debug.log?

   The rest of the error log:

   The block chain is on an external USB hard drive since it’s too big for this old Latitude’s primary hard drive. It’s probably something relatively simple but of course unknown to most since the other threads got no response.

   Can you post the full debug log or at least the last 50 lines?

   I have no clue what the additional information is. Really need bitcoin core’s debug.log, not OS information

   The debug file is attached. Bit Coin Core crashes when started so the programs features are unavailable. The error can be reproduced by reinstallation but that’s not going to resolve anything.

   So your database is clearly corrupt and you suspect there’s something wrong with the program. Why is that?

   The block chain is being corrupted during the operation of the program. File corruption has been a continuing problem since the beginning of information technology. The more data that has to be handled the more likely these issues will happen.

    You started off with a “bitcoin-qt.exe can’t start”, now you’re admitting the blockchain was corrupted before that. Plus there’s already this issue for that: #6528

    Ok, your chainstate database is corrupted. You can regenerate it by passing -reindex as a command line argument.
