Here is the solution that worked for me: Uninstall EA App, Wild Heart and Steam, create a new administrator account and reinstall EA App, Wild Heart and Steam. After you uninstall EA App, just to be on the safe side, remember to go to the root folder (mine is at C: Program Files/ Electronic Arts) and delete the whole empty EA folder.
To create a new administrator account on your PC (Win 11), go to Start--Right click on your avatar--Change account settings--Family & other users--Other users (you may try "your family" but I prefer "other users")--Add someone else to this PC--Enter a Microsoft email address which is different from your main account--Add the new email address as a new account and make this account as an Administrator.
After creating the new administrator account, log in to this new account and download Steam. Then download and reinstall Wild Hearts through Steam (check the box to create a desktop shortcut for the game).
After the installation, use the shortcut to run Wild Heart. Steam will ask you to download EA App, follow the instructions and install EA App, and the game will continue to run.
Wait for a few seconds and you should be able to see the loading screen of Wild Hearts now.
I don't know the mechanism behind the account trick, but it did work for me. Hope it also works for you.
@dynisa Oh my god that actually worked, thank you so much.
Also seems like you can't just switch back to your old account after installing the game, still the same issue.
