1.) A workaround that helped me: Install EA Desktop on another PC, or have someone send the files from "C:\Program Files\Electronic Arts\EA Desktop" where the app works.
2.) Start Powershell and add the EA services with the following two commands:
New-Service -Name "EABackgroundService" -BinaryPathName "C:\Program Files\Electronic Arts\EA Desktop\EA Desktop\EABackgroundService.exe"
New-Service -Name "EAAntiCheatService" -BinaryPathName "C:\Program Files\EA\AC\eaanticheat.gameservice.exe"
3.) The hardest part. On the computer where the EA app works, use the registry editor to search for and export the entries that are related to "EA App" and in my case to Fifa 23, i.e. "Fifa".
Then import the exported entries into the registry, where the EA app cannot be installed.
This is how it worked for me. The game then has to be downloaded completely again, but the EA app starts and everything is there. An update of the EA app is still not possible.
I would also provide the installed EA app and registry entries (which still need to be customized), but I don't think that's possible due to copyright regulations. sorry
