Brute force 4 missing Electrum words isn't cheap, so i have to ask whether you already think another way to restore your Bitcoin? For example,
1. Check whether your OS made backup of that .txt file. For example, Windows have feature "Enable Previous Version" which AFAIK enabled by default.
2. If you accidentally delete Electrum wallet file, you could use file recovery tool software (such as Recuva) to restore the file.

There are two tools that I know that you can use to brute force the missing 4 words BTCrecovery and FinderOuter Bitcoin recovery tool.
You can find the source of BTCrecovery here https://github.com/gurnec/btcrecover
And FinderOuter here https://bitcointalk.org/index.php?topic=5214021.0

FinderOuter is more user-friendly, but 2048^4 is rather large combination and FinderOuter lacks GPU acceleration.
