If you are trying to open a PCK file for Godot 4.5, you need the latest version of PCK Explorer compiled from source. It has already been updated along with Bruteforcer, but has not yet been released.
I've sent you the file, sorry it was very long because my internet connection is very bad when it comes to upload speed 10-50kb/s. I was trying to open the package again exe + pck through GDRE but it returns with PARSING error or smth. Could u generate the key for me by using the 1.0.2 ver? I am using the latest bruteforce version 1.0.3 based on the github.
I'll try once again with Bruteforcer 1.0.3 version, let's see if do it twice will work. If not, could you give me the source for the 1.0.2 bruteforcer?
