I've updated USharp Bowling To Run Primarily On C++/Blueprints For Improved Flexibility and Compatibility With Upcoming Versions of Unreal Engine. The older version of USharpBowling was archived in the CSharp4-24Version branch, which is only compatible with UE 4.24 and has several bugs that haven't been fixed.
You can also find the old C# scripts inside the Managed/OLDREFUSharpBowlProject folder. I'll likely reimplement certain c# features in the future.
If you download this project, make sure to update the UProject file to remove whatever plugins you do not have.
I'll likely not update the itch.io build of USharp Bowling with the new C++ version. It kind of defeats the purpose of showing off the potential of c# scripting. Keep in mind the itch.io version uses a previous version of USharp bowling that runs on an older version than UE 4.24.
Feel free to check out USharp if you want to try writing c# scripts for UE4: https://github.com/pixeltris/USharp
You can play the game on itch.io. https://tanman555.itch.io/usharp-bowling
