You need to open up the visual studio installer click on modify and goto individual components and search c++ make sure both C++ 2019 Redist are selected maybe c++ cmake tools, c++ cli build tools v141 and msvc v142 vs 2019 c++ are checked and then hit modify. it will download and install. and will more than likely want a reboot, so do that, then do the right click on that uproject and select the unreal version. after it goes away then double click and it will say you need to build it for the project. do that. then check to see it working, then after close it. copy the folder from plugin. into your unreal versions /UE_4.23/Engine/Plugins folder.
