I have just created an account, downloaded the trial version and started following the "Space Rocks" tutorial to learn how to use GameMaker and this "Project Directory Modified" window keeps popping up. It happens even if the project is empty. I'm not using OneDrive or Dropbox or anything like that in the project. I'm not using source control. I tried disabling the antivirus (Avira) and firewall and tried running GMS as admin with no success. GMS is installed on my SSD and the project is on my HD. I tried swapping the install to the HD to no success. Also tried moving the project to the SSD to no success. I saw other old posts talking about this but none happening with an empty project like this and nothing seemed to fix it either. I know there is a way to disable the File Watcher but that hurts the possibility of using source control from what I've read.
