absolutePath returns broken path

[Onur Balcı]

if the asset path contains "Assets" keyword absolute path returns invalid path

Example Asset Path: Assets/ExternalAssets/Sprites/foo.png

Project Path: D:/Projects/Test

Expected: D:/Projects/Test/Assets/ExternalAssets/Sprites/foo.png

Current: D:/Projects/Test/Assets/ExternalD:/Projects/Test/Assets/ExternalAssets/Sprites/foo.png
