If all two parts are hidden in my home, once they are found by thieves, I am died. What should I do?

Hide them better and also have off site back ups.

You can hide a piece of paper in hundreds of places in your home a thief would never find it. Under a floorboard. Inside a door. Inside some piece of furniture or equipment. Inside some fitting or socket.

And having your only back ups in the same place as your wallets themselves (i.e. at home) is incredibly risky as a single event can still wipe you out. Everyone should have at least one off site back up.

How can thieves or ordinary hackers crack it?

I already showed you a link where someone cracked a fingerprint reader on a $1000 smartphone in 3 minutes. The fingerprint reader on a $20 USB drive will be trivial by comparison.

Can your solution deal with such extreme situations?

Yes. Unless the thief has a month to systematically disassemble and dismantle my entire house, they won't find the back ups I have hidden at home. And even if they did, they wouldn't be able to access my wallets since the other necessary information is backed up off site.
