user140415: I'm a total newbie who's into Bitcoin. I was in the middle of downloading Bitcoin core(78%) when my computer just freeze for hours that I have to force shutdown without closing the Bitcoin Core properly.
When I rebooted and started Bitcoin Core again, it shows "Error Reading from Database" and close itself. I repeated the process and it's the same.
I have checked on the debug file and seems like there is a corruption of data mismatch.
Does anyone have experience with this situation? Please help me, it took me 5 days to reach this download progress, and I definitely would appreciate to not start all over again T.T

Thank you!!!!!

user139612: As indicated by the logs, your chainstate database is corrupt. You can fix this without re-doing IBD by restarting your node with -reindex-chainstate. For more information on the differences between -reindex and -reindex-chainstate, check out When should I use -reindex-chainstate and when -reindex
From the comments, it seems you are using bitcoin-qt on Windows. I don't have access to a windows machine, but the command you need to run is something like the following:
<Path\to\bitcoin\executables>\bitcoin-qt.exe -reindex-chainstate
