EA App stuck at 0% while updating

I was having the same issue too! 

I fixed it through the following steps (on Windows 11 OS):

1. Navigate to File Explorer
2. Go into 'Program Files' folder
3. Go into 'Electronic Arts' folder
4. Go into both 'EA Desktop' folders
5. Scroll down until you find the 'App Recovery' file, double-click it
6. A confirmation window will popup with the option to 'clear cache'
7. After cache is cleared, the app should restart on its own and the update will start again.

Hope this helps!
