Can I recover my passwords?

I used Avast Free Antivirus for years, including the free version of password manager. I moved on a new pc recently and realised that the password manager is no more free. Is it normal?
Can I recover my old passworld by copy pasting the file from my older computer? I can’t boot it anymore (something broke) but I still have acess to the file.
I should have exported my password but I didn’t think about it and it’s now too late TT The problem is that I now realise I counted on Avast for a lot of think and I’m really stuck without the data it have. Is there any solution ?
