Thanks for the bug report

using trackcolor prop fixes the issue

AFTER

        <Switch
          disabled={true}
          value={true}
          trackColor={{false: "blue", true: "red"}}
          />

probably the default color of the BackgroundDrawable is by Default transparent. The background must be gray and showing just the background, then for some other reason when you change the background color they both become transparent

I saw similar issue fixed with pr #29830 but I don't think it is related and I don't think it is worth investigating. Thansk a lot 🙏
