Can't build Solar2D project with plugins (Windows 10, Android) - plugins not loading, missing folders

Hello, I can’t build a project with plugins (plugin.utf8, plugin.zip) in Solar2D Build 2025.3718 on Windows 10. The simulator doesn’t load the plugins, the folder C:\Users\User\AppData\Roaming\Solar2DPlugins is not created, and the Android build fails with an error. The log shows:

WARNING: there was an issue while downloading simulator plugin placeholders:  
Unable to find plugin 'plugin.utf8' for platform 'win32-sim':  
  Locally: no directory C:\Users\User\AppData\Roaming\Solar2DPlugins\com.coronalabs\plugin.utf8  
  Solar2D Marketplace Directory: skipped because marketplaceId is not set  
  Solar2D Directory: directory was not fetched  

My build.settings:

settings = {  
    plugins = {  
        ["plugin.utf8"] = { publisherId = "com.coronalabs" },  
    },  
    android = { usesPermissions = { "android.permission.INTERNET" } },  
    orientation = { default = "portrait", supported = { "portrait" } },  
}  

What I’ve tried:

  • Reinstalled Solar2D, deleted C:\Users\User\AppData\Local\Corona Labs\ and C:\Temp\Corona Labs\.
  • Checked internet connection (it works, also tried VPN).
  • Tested with a new project—same error.
  • Without plugins, the build succeeds.

Every time I restart the simulator, there’s a 5-second plugin loading delay before launch. The plugin works in the simulator even if I don’t specify it in build.settings, but as soon as I add it, the 5-second delay appears and the build fails.

I completely deleted all Solar2D-related folders I could find, including Gradle, and downloaded the latest version, but new projects with any plugin still won’t build.

The folder C:\Users\User\AppData\Local no longer gets created even after a fresh Solar2D install. I really need help with this.

try also to delete those folders and build again (not sure about the folders in blue rectangle, but delete the 2 folders above

after deletion … first build will take long because it will download them again
