I've been trying to do some file cleaning on my mac and I think I've accidentally deleted one of the "Find My" app files and now each time I open the app, the map in blank. I've attached a screenshot so you can see. Anyone can help?
Luis has a point. The reason I suggest reinstalling is because you can do it from Recovery Mode and there's nothing to download. The combo update may work.

Before you do a full reinstall, try running the 10.15.3 Combo Update - even if you are already running 10.15.3. The Combo may sometimes replace missing or damaged system files. At least it does not hurt to try.
Try restarting your Mac. If that doesn't work, you may have to reinstall Catalina.
