Just going to mention that it is bad practice to store working projects in OneDrive and other cloud sync solutions as concurrent access by both GMS and the sync software could in theory mean some files get corrupted. I have no insight into how likely it is, but using OneDrive as a backup (you do have backup of some sort implemented, I would hope, since you were agonizing about something not working) while using a non-synced, local drive location for the project directory is supposedly a better idea.
