Windows 7 x64
Godot Engine v2.0.3.stable.official
This problem started after I moved and renamed some files (scripts, images, scenes, sounds) in a project's resources folder for testing purposes.
After finishing testing, I made my best effort to restore their names back to the way they were before, but I may have failed, and now Godot's FileSystem panel is stuck at "Scanning Files, Please Wait.."

The console/cmd window is meanwhile being spammed with "ERR OUT OF MEMORY" error messages as shown in the following screenshot.

Reopening the project does not help. I have also tried rebooting my computer.
Is there any way I can troubleshoot this issue, such as finding out which filenames Godot may be failing to find in the project's resources folder (assuming that is the cause of the problem)?
Thanks in advance for any input on this issue!
