Unable to run Flutter project on Android after update

I've been trying to get my Flutter project to run after upgrading it to 2.10.4 and it's been a headache from the start. The project runs fine on a browser, but I'm having difficulty running on an Android emulator. I think I'm at the last hurdle, but I'm stumped right now. I'm receiving this error when running on VS Code:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Failed to install the following SDK components:
      build-tools;30.0.2 Android SDK Build-Tools 30.0.2
  The SDK directory is not writable (C:\Program Files (x86)\Android\android-sdk)

Here's my Flutter Doctor:

Here's the part that keeps getting me. I'm seeing I need to run flutter doctor --android-licenses and this is what I get:

PS D:\Documents\Flutter_Projects\glance> flutter doctor --android-licenses

Error: Could not find or load main class Files

I have no clue where to go from here. Any help would be greatly appreciated here. Thank you in advance.
