EA App won't launch ME Andromeda after moving installation folder

Hi all, posting here at a customer care adviser's suggestion in hopes someone will know how to fix this.

Long story short, the EA App won't let Steam (or me) launch ME Andromeda after I used Steam's inbuilt tool to move the game's installation folder to another drive due to lack of space in the original drive. Most of the time it throws up the attached error, although on occasion it instead says it's an issue on EA's end. The game shows as installed on Steam but not on the EA App.

Have wasted several hours and tried multiple steps without any of them working as detailed in case number #257891247 - or I can provide a chat transcript if easier.

Windows 10 PC, the game was launching and working just fine until the installation folder move. Nobody else uses the device and I don't have any other EA accounts. Have tried the following steps multiple times: uninstalling and reinstalling both the game and the EA app, updating and repairing the app, clearing the app cache, verifying and re-linking the Steam installation path, verifying file integrity on Steam, downloading a different game on the app, clearing AppData registry conflicts, restarting my PC, resetting the EA Background Service, and a couple more things.

Would be tremendously grateful for any help!
