Magic Earth maps app won't open

Those instructions said to just enter something in command line, but where would the app be to reinstall it?

Sorry, if the issue filed at the GitLab is the source of your trouble (and it certainly matches your description), then what I said wouldn’t help until the bug is fixed anyway. If you’re in a hurry, you could try something else …

Alternatively you can try to install the current Magic Earth version using Aurora Store, which is an Open Source client for the Play Store giving you access to cost-free Apps there with an anonymous account.
In this case be sure to use Aurora Store’s Blacklist manager to blacklist every App which you didn’t install via Aurora Store (yes, these are many) to not confuse the system, Aurora Store or yourself with updates which Aurora Store shouldn’t offer .
