Why isn't my Audi A5 engine starting?

I have a 2018 Audi A5 and it suddenly stopped starting. The lights and everything else seem to be functioning properly, but the engine won't turn over. What could be the issue and how can I fix it?

First, check your battery to make sure it has enough charge. If the battery is fine, it could be a problem with the starter or ignition system. I suggest taking it to a certified mechanic for a proper diagnosis and repair.
