4.19.2 you cannot create a new C++ project if files in project folder already, which comes from this project starting remotely and then cloning it locally.
So far I am attempting to rename the existing BattleTank folder and create the new UE project, then I will copy the git related stuff into the new folder.
[EDIT] This has been a constant source of confusion/mistake for me…I needed to have an extra level of subfolder battletank/battletank the first for the main project and git related stuff and the second level for the UE project. How to fix it is the begging question now.
[EDIT AGAIN]
Back on track with this move project info: https://www.worldofleveldesign.com/categories/ue4/ue4-change-move-project-folder.php
