It is so sad that your previous keywords have been lost. Everyone has had this problem. Wallet privacy is a personal matter; why is it lost, or how is it lost? They do not care about them; they consider them straightforward things and neglect them. Later, when they have problems with these, they ask for help. There is no point in asking for help because no one can remove these private keys. If you lose it, there is no way to find the wallet.

Since you have lost this pen drive, look carefully where you have kept it or remember where you have written the private key. It would help if you had your wallet's private key to get your wallet back. Make a new address and save it well so you don't make such a mistake later.
Be careful now so that no such problem occurs in the future.
