So, for anyone that find this post. This fixed for me:
#0 - Quit Epic Launcher (right click tray icon > exit). If you don’t quit completely, changes will be reverted.
#1 - Navigate to
C:\Users[username]\AppData\Local\EpicGamesLauncher\Saved\Config\Windows
#2 - Open
GameUserSettings.ini
#3 - and add lines to the end under [Launcher] like the following:
[Launcher]
CreatedProjectPaths=D:/ParentFolderOfYourProject
CreatedProjectPaths=D:/DifferentParentFolderOfYourOtherProject
Note: Do not type in the project folder itself or else it won’t work.
