Error after updating package manager

After updating the 2d packages in package manager i got this error.
Does anyone know, why ?
I just get a compiler error and this error

Library\PackageCache\com.unity.2d.common@4.2.1\Editor\InternalBridge\TexturePlatformSettings\TexturePlatformSettings.cs(147,23): error CS1061: ‘TextureImportPlatformSettingsData’ does not contain a definition for ‘alphaSplitProperty’ and no accessible extension method ‘alphaSplitProperty’ accepting a first argument of type ‘TextureImportPlatformSettingsData’ could be found (are you missing a using directive or an assembly reference?)

I found it.
In Unity menu : Help - Reset packages to default.

:slight_smile:

I got rid of this error by de-updating com.unity.2d.common from 4.2.1 to 4.2.0
