Can’t launch my game They Are Billions via EA App

Hello,

I'm experiencing an issue when trying to launch "They Are Billions" through the EA App.

Each time I click "Play", I get this error:

"The game could not be launched due to an error on our end."

I originally purchased the game on Origin, and it is correctly listed in both:

My EA App library
My purchase history

However, since the migration from Origin to EA App, the game no longer launches.

Here's what I’ve tried:
Cleared EA App cache
Reinstalled the game
Launched the .exe directly as administrator
Checked permissions and install path
Verified firewall/antivirus settings
Fully uninstalled and reinstalled EA App (including deleting all EA-related folders from AppData and ProgramData)
Made sure I'm logged into the correct EA account

None of these resolved the issue.

Support problem:

I attempted to open a support case, and one was created. However:

When I click on “Resume Case”, it just redirects me to troubleshooting articles
I’m unable to upload files, continue the conversation, or reach a support agent
The ticket seems stuck, and I’ve been warned it will close automatically unless I take action — which I can’t

Could this be a licensing issue caused by the Origin → EA App migration?

I would appreciate any assistance, or for this case to be escalated to someone who can manually verify the license on my account.

Thanks in advance.
