What windows are you talking about? Is another window popping up?
You can also try to have the installer on the C drive instead of another one. And you might have no anti-virus but sometimes Windows Defender is the problem.
In the logs I can see when trying to install mamba it immediately fails. There might be something killing mamba process.
To be honest I don’t know. But we can try to manually install mamba.
It should manually install mamba at the right place. We will see if it fails or not. If it doesn’t fail, you can try again using the installer (it will probably fail again at the install_mamba part but might succeed creating the environment! If the environment is correctly created, the game should work.
Maybe a problem with the file then… You can try to redownload the game and see. Or, you can manually download micromamba at https://micro.mamba.pm/api/micromamba/win-64/latest and replace the micromamba.exe by the one you downloaded (make sure to rename the new .exe into micromamba.exe
