It may be the file is a hidden state. So check the file properties the file is hidden state or not? If hidden the file means, Please remove the access, then to encrypt the files.
AxCrypt account and AxCrypt app are required to open/decrypt the AxCrypt encrypted files. Without the AxCrypt app, we cannot open/decrypt the encrypted files.
