Godot version

v4.0.dev.20211108.official.596865366

System information

Windows 10 64bit - Vulkan API 1.2.141 - GeForce GTX 1660 SUPER

Issue description

When you create a TextureAtlas from PNGs Godot as you to restart and can not start anymore without remove PNGs .import files.

I didn't find any related issue in the past months on GitHub tracker. I only tried it on Windows. I thing it's the same with other images. Same behavior in Godot_v4.0-dev.20211027.

Steps to reproduce

  1. Create a blank project
  2. Add PNGs (I used https://www.kenney.nl/assets/toon-characters-1)
  3. Select PNG in editor (Screenshot 1)
  4. Select "Import" tab on left sidebar
  5. Import as TextureAtlas
  6. Select "Atlas file" and give it a name (the name does not matter)
  7. Select "Reimport" button
  8. Select "Save Scenes, Re-Import, and Restart" button
  9. Wait the engine restart and display a blank pop-up named "Load Errors" (Screenshot 2)

@gustavi Can you reproduce this on 3.4 as well, or only in master?

EspeuteClement added a commit to EspeuteClement/godot that referenced this issue May 9, 2022
The crash was caused by the reimport_files function trying to reimport the atlas file multiple times using multithreading, which caused deadlocks and hang the editor.
This fix prevents files from being added to the reimport_files array if they are already present inside of it.

Fixes godotengine#54817
