I know a way to crack it if and only if the password is less than 10 characters(if unlucky could take 5 years to crack it, but maybe not, I would need to research more to be sure)
The way is the most common attack for this case, brute force, it would require a lot of computational resources that me as a poor and not smart geek can't handle(I don't even have a computer/notebook, literally I'm phone posting), and also I wouldn't do it for free if you ask me(the only thing I can give is some idea that may work)
Maybe you can do yourself if you have an awesome computer that can handle it(quantum computer), but if you don't have one here's my idea, get computational power from PEOPLE ONLINE! you can fake it as some program you distribute for "free"(let they know in the user agreement that you will do it, so they won't complain cause ur just using some computer power like they do it with Chrome/Firefox or the "free" Microsoft OS, you ain't stealing their data(maybe the software I listed before do it, but idk,idc)) or you can even make some backdoor or sh1t that lets you use their computer power, when you get this computational power the next steps are simple(basically divide and conquer method):
1. Make a wordlist of many sizes length(1-9 characters set, I think more than it would take an eternity, kinda impossible)
2 Divide this wordlist for each computer you have to do the attack(send each part of this wordlist for each computer you have available, e.g. You have a 10 words length wordlist and 5 computers, give each computer 2 words(2*5=10) and the file you want to crack, each one of them will start the attack)
3. Send the divided wordlist for each computer with the file you want to crack
4. Wait(??? drink some coffee or take a sh1t)
5. If you lucky the correct password will be sent back to you from some random computer or you will receive back a list of concluded failed attacks(this is important), get that list of failed attacks to filter your wordlist
