Showing this error while trying to debug an App in Flutter

I’m recently switched to linux from windows, and I set up all flutter things in that, but when I’m trying to run, showing this error on terminal

lib/main.dart:1

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> java.net.URISyntaxException: Illegal character in opaque part at index 2: D:\Documents\FLUTTER\flutter practice\test app 1\login_shared_pref\build\app\intermediates\flutter\debug\flutter_assets\AssetManifest.json

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
