Update:
I realized processing was throwing another error:
Processing found an Android SDK, but is not valid. It could be missing some files, or might not be including the required platform for API 29. If a valid SDK is available in a different location, click "Locate SDK path" to select it, or "Download SDK" to let Processing download the SDK automatically.
It could be that I either downloaded the wrong file or it lost certain files due to the unzipping process. I’m not too sure, but I’ll still try to move it to the D drive.
Summary
I’m also using win10 64bit
