Can't install GOG Galaxy in Lutris under Bazzite

Hi,

First-time Lutris user here. I wanted to install GOG Galaxy in Lutris but during the installation, I get 3 pop-ups telling me .net framework 4.8 should be downloaded and installed first. I clicked YES every time but in the end, it says “Installation complete!” and when I launch GOG, it can’t find the executable (GalaxyClient.exe). I’ve checked and the file is indeed missing. I should add that after having clicked 3x YES in the pop-up to install .net framework, my browser has 3 tabs opened on Download .NET Framework 4.8.1 | .NET. Am I supposed to download and install it myself (and how?) or should the installer do it by itself?

Thanks!
