Bitcoin Core v.23 import non-public key query

Hey.
I’ve a non-public key which I’ve imported (importprivkey in console) into bitcoin core v.0.17.1. Stability for instance 1 bitcoin

1. Made a transaction of 0.1 bitcoin to a P2PKH tackle. The remainder is 0.9 bitcoins.

2. Eliminated bitcoin core v.0.17.1 and pockets.dat

3. Put in bitcoin core v.23.0

4. Imported the non-public key. Stability 0 bitcoins.

5. There are 2 transactions:

   0.1 bitcoin (transaction)

   0.9 bitcoin (I believe that is change, despatched to bech32 beginning bc1…)

Do I perceive appropriately that I misplaced my bitcoins, which had been despatched as change to the bech32 tackle, or bech32 addresses are generated from one non-public key and the change went to that tackle? Is it doable to revive them?
