Problem with unlock /decrypt Bitlocker external hard drive with correct password

I have an external disk with a capacity of 2 TB encrypted with BitLocker. I decided to decrypt disk on my Dell Latitude E5530 (Windows 10 after upgrading from Windows 7). I entered the correct password and started the decryption process. I decided to do it another time and I stopped the decryption process (at the level about 4.2%). Later I safely disconnect it from system. When I connect it next time to the USB port and I tried to unlock with correct passport, the system information was, that password is not correct. How can I repair it, unlock or decrypt if it not working? I don't have recovery key.
