I am sorry to say, If the recovered encrypted file is corrupted then AxCrypt will not able to decrypt the same.
But we have a feature called Try Broken File. You can try to decrypt the corrupted AxCrypt encrypted files by navigating the menu File | Options | enable Debug from the AxCrypt app.
Now you are able to see the Debug the menu in the AxCrypt app. From the debug menu you have to choose Try Broken File menu option.
Now you will be prompted for file selection. Select the corrupted encrypted file and then AxCrypt will try to decrypt the file. If successfully decrypted, then you are able to see the decrypted file in the file location. Otherwise, AxCrypt can’t decrypt the same.
