The program has already crashed twice, with nothing remotely resembling a human friendly error message, like, what it was it could not read (or where). it just crashes with various very generic messages. This is the only program that crashes regularily on my pc and i have no idea why, because the error messages are too generic like "cannot read database" hey! how about also writing on what drive, and in what dir, and what went wrong..
i don't feel like i would dare to trust this software with my bitcoins when it can't even bootstrap itself from the net, when it doesn't even seem to know itself why it crashes.
Secondly, all of the important error information ends up in the debug.log file found in the Bitcoin Core datadir, not in the error dialogs. If it is crashing regularly, you may have a hardware failure somewhere as Bitcoin Core is known to be very hardware intensive. However the software itself can't tell you that, it just knows that it tried to read from the database and got back garbage that it wasn't expecting. And it does know why it crashes, it couldn't read the database. Why that happened, it does not and cannot know.
