Can't open Bull Cow Game first time

After downloading and extracting the BullCowGame-starter-kit, I had to specify which program I wanted to use to open the project; I selected Unreal (ver. 4.26.0). Afterwhich, I tried booting it up through the engine’s browse feature and was hit with the warning that BullCowGame was built with a different engine and needed to be recompiled; I told it to recompile, then it recommended making a copy as to not disturb the original; I told it to make a copy and now I’m getting hit with this error:

Screenshot (20)

I have looked at many other posts having the same issue but most posts that I have found fixed themselves without explanation, so I am lost as to what to do to fix this.
Here is the log file for the updated copy it asked me to make:

Do you have an antivirus that could be causing this to not have permission creating this file?

I appreciate the suggestion! But sadly that didn’t work.

However! I just managed to find the solution. It wasn’t giving me the option to allow permissions to the file (such as running as administrator), but I was able to run Unreal itself as administrator, then open the file through browse projects, and that worked!

I came across that same issue of needing to convert to a copy for use with 4.26, and running everything using admin privileges. I also needed to install the developer SDK so UE4 could work with the game. It seems to have done the trick. Thanks anyway @KeegaFloof because your question helped me solve it my own way.
