If the file is only encrypted and not corrupt there is  a fair chance of recovering the password.
I have been recovering lost and forgotten passwords for over 20 years now.
Your only problem is to find somone you trust enough not to run away with your coins.
My success rate is about 80% on pc files and under 20% on bitcoin wallets.
Feel free to reach out, otherwise I wish you luck in finding a trustworthy person.
