I have 4.2 installed with no issues. You don't need a newer release if you are only using it with the PS3 because those files haven't changed in 10 years.
Bruteforce is not built on .NET as far as I know. It would likely be built on the .NET Framework if it was and most of the changes are on .NET Core (now called .NET) rather than the .NET Framework (which the dynasty editor was built on). .NET 7 is going of of support next May while .NET Framework 4.6.2 will be supported for another 3 years and 4.8.1 (released last year) will likely be supported at least until 2030.
