I lost my password to an electrum wallet

I need a bitcoin developer to confirm me if there's a way to convert the array of strings, which are the seeds, to private keys and then start checking if there funds on each address.

this is not how brute force supposed to work. you have to think about removing all the bottlenecks and optimizing the algorithm as much as you can instead of adding more bottlenecks. right now your work with "strings" and "printing them" are two huge bottlenecks that slow down anything you want to do.
there is also another step that you are missing which is checking the correctness of the checksum of each seed phrase before moving on to trying to create private keys.

What do you mean by saying bottlenecks? I don't get it? I can't think of a more productive way to do it. First take all the possible combinations, and then run a program that checks every line.

About that, on BIP39 I've noticed that it doesn't matter the checksum. Whatever seed you'll submit on electrum it will take it.

1. you are working with strings, they are inherently slower than integers (or bits to be more exact).
2. that also means you have to keep converting back and forth between strings and bytes when creating checksum while also having to normalize the text with Electrum defined algorithm
3. printing the result whether to UI or to file is also an extremely slow process (that is why your UI hangs when the number of words is higher than 4-5).
4. you don't have to produce ALL possible combinations, it can be reduced by 94% if you validate checksum! (about 6% are correct in BIP39 and i believe it is the close to same value for Electrum).

it should matter, if your checksum is invalid then this line will return false (an invalid seed phrase).
same with BIP39, if your SHA256 checksum is invalid it will be rejected (reference implementation).
