IllegalStateException in com.squareup.picasso.BitmapHunter

Question

an exception report appears in the Android Vitals, without an exact trace:

Exception java.lang.IllegalStateException: Transformation circle mutated input Bitmap but failed to recycle the original.

  at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1067)

I roughly understand which part of the code is causing the error, here it is:

    public static class CircleTransform implements Transformation {
        @Override
        public Bitmap transform(Bitmap source) {
        
            int size = Math.min(source.getWidth(), source.getHeight());

            int x = (source.getWidth() - size) / 2;
            int y = (source.getHeight() - size) / 2;

            Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
            if (squaredBitmap != source) {
                source.recycle();
            }

            Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

            Canvas canvas = new Canvas(bitmap);
            Paint paint = new Paint();
            BitmapShader shader = new BitmapShader(squaredBitmap,
                    Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
            paint.setShader(shader);
            paint.setAntiAlias(true);

            float r = size / 2f;

            canvas.drawCircle(r, r, r, paint);

            squaredBitmap.recycle();
            return bitmap;
        }

        @Override
        public String key() {
            return "circle";
        }
    }

On test devices it is not possible to catch this exception; it occurs only for some users. If anyone has any ideas on how to fix this exception I would be grateful.
