Writing a MemoryFile() with rio cogeo back to a file on disk

Question

I am not sure why I am struggling with this one but I would appreciate your help. I want to read a geotiff, process with rio cogeo and then save it as the hash of that file. I am doing something odd.... Here is my function. Any ideas?

try:
        with MemoryFile() as mem_dst:
            dst_profile = cog_profiles.get("deflate")
            cog_translate(filepath, mem_dst.name, dst_profile, in_memory=True)
            sha1 = hashFile(mem_dst)
            with rasterio.open(mem_dst) as src:
                with rasterio.open(
                    f'{output_folder}/{sha1}',
                    'w',
                    **src.profile
                ) as dst:
                    dst.write(src, 1)

    except Exception as e: 
        print(e)
