Android build keeps failing

Hello, I've been using Unity 2021.3 LTS version to make an application for Android, but whenever I try to build it in the build settings, it always comes up with an error saying "Android SDK is missing build-tools" or "Android SDK not found". This is surprising because I have the latest version of Android Studio installed with all the latest build tools, and all of them have been located in the Preferences settings in Unity. I have also the build tools which Unity Hub installed when first installing Unity, which was the default build tools, but either way, Unity does not seem to recognize any of the SDKs, NDKs, or other build tools installed. Any help would be much appreciated!
