I can’t really see the cracks, but that is definitely something that support will need to address. They can get you set up with a replacement lens.
You might want to check over all of the optical components and provide pictures for support to take a look at. There are several windows to clean, and if your mirror was smudgy, you might want to check all of them so that if there is anything else, they can take care of it at the same time.
There are pictures here of what to wipe/check.
While you are waiting, you can check these out. (I would not try to run the machine again with a cracked lens in it.)
