Re: "DisplayName field missing from registry"

Reason: This happend when Origin can't find the game in your library.

SIMPLE SOLUTION

1. Navigate to “Apex Legends” in the Origin store
2. Add the game to your library
3. On the “Download-Window” popping up just click next
4. The game won't be downloaded again, the installation will be automatically detected by origin
5. The “Cloud-Synchronisation” will start. After it finished (approximately 2 seconds) the game will start as normal.
