Android Problem loading widget - without errors in the logcat

I created an analog clock widget in java, and for some reason I get "Problem loading widget" all the time, the only things I get from the logcat when I try to place the widget are:

2020-11-18 19:19:13.162 9482-9482/? E/Zygote: isWhitelistProcess - Process is Whitelisted

2020-11-18 19:19:13.196 9482-9482/com.l_es.analogclockcustomization D/ActivityThread: setConscryptValidator - put

and the widget is only a black square with "Problem loading widget" on it.

here is the widget class:

public class MainWidget extends AppWidgetProvider {

    static RemoteViews views;
    //preferences
    private static SharedPreferences custClockPrefs;
    //number of possible designs
    private static int numClocks;
    //IDs of Analog Clock elements
    static int[] clockDesigns;

    public void onReceive(Context context, Intent intent) {

        numClocks = context.getResources().getInteger(R.integer.num_clocks);
        clockDesigns = new int[numClocks];
        for(int d = 0; d < numClocks; d++){
            clockDesigns[d] = context.getResources().getIdentifier
                    ("AnalogClock"+d, "id", context.getPackageName());
        }
        //find out the action
        String action = intent.getAction();
        //is it time to update
        if(AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action)) {
            views = new RemoteViews(context.getPackageName(),
                    R.layout.clock_widget_layout);

            AppWidgetManager.getInstance(context).updateAppWidget
                    (intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);

            custClockPrefs = context.getSharedPreferences("CustomClockPrefs", 0);
            int chosenDesign = custClockPrefs.getInt("clockdesign", 0);
            if(chosenDesign >= 0){
                for(int d = 0; d < numClocks; d++){
                    if(d != chosenDesign)
                        views.setViewVisibility(clockDesigns[d], View.INVISIBLE);
                }
                views.setViewVisibility(clockDesigns[chosenDesign], View.VISIBLE);
            }

            Intent choiceIntent = new Intent(context, ClockChoice.class);
            PendingIntent clickPendIntent = PendingIntent.getActivity
                    (context, 0, choiceIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            views.setOnClickPendingIntent(R.id.custom_clock_widget, clickPendIntent);

        }
    }

}

here is the draw function I use in order to draw the clock:

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    final float w = (float) getWidth() / 2;
    final float h = (float) getHeight() / 2;

    final int saveCount = canvas.save();
    canvas.translate(w, h);
    final float scale = Math.min((float) w / mDial.getIntrinsicWidth(),
            (float) h / mDial.getIntrinsicHeight());
    if (scale < 1f) {
        canvas.scale(scale, scale, 0f, 0f);
    }
    mDial.draw(canvas);

    final float hourAngle = mTime.get(Calendar.HOUR) * 30f;
    canvas.rotate(hourAngle, 0f, 0f);
    mHourHand.draw(canvas);

    final float minuteAngle = mTime.get(Calendar.MINUTE) * 6f;
    canvas.rotate(minuteAngle - hourAngle, 0f, 0f);
    mMinuteHand.draw(canvas);

    if (mEnableSeconds) {
        final float secondAngle = mTime.get(Calendar.SECOND) * 6f;
        canvas.rotate(secondAngle - minuteAngle, 0f, 0f);
        mSecondHand.draw(canvas);
    }
    canvas.restoreToCount(saveCount);
}

Here is my layout file of the widget, keep in mind that I set at every time 2 out of the 3 to be with visibility of "gone":
