Failed to launch game An error on our end caused the launch to fail.

For more than 6 weeks I've been attempting to troubleshoot why 1 EA game out of 5 gives me the "Failed to launch game An error on our end caused the launch to fail. Try again a little later," error message every time I try to play. 

All other games accessed via the EA app launch just fine, only SimCity fails. The error messages occur as follows:

1. I login to my EA app, select SimCity, and click Play.

2. An error message pops up that reads, This game requires permissions This game requires administrative privileges. Do you want to grant access and launch the game? OK CLOSE

3. Selecting OK results in another error message pop-up that reads, Failed to launch game An error on our end caused the launch to fail. Try again a little later. OK

I've done every single thing I can find to troubleshoot/resolve this issue, including every step listed on this page: https://help.ea.com/en/help/ea/ea-app/game-download-install-load-troubleshoot/

Everything is up-to-date, including the EA app, the game, and my operating system and graphics drivers.

I've also followed a fix recommended by the chat advisor, which was to uninstall the EA app and delete the associated registry keys.

Clean boot with all non-Microsoft services disabled doesn't resolve the issue.

Clearing the cache doesn't resolve the issue.

Uninstalling the game, the EA app, then reinstalling doesn't resolve the issue.

Disabling antivirus and firewall doesn't work.

Running the EA app or the SimCity executable as administrator doesn't resolve the issue, nor does running them in compatibility mode.

Controlled folder access configuration changes don't resolve the issue. Whitelisting the game for controlled folder access doesn't resolve the problem.

Repairing the game doesn't resolve the issue.

I've done all possible fixes listed above multiple times over the course of 1 - 2 months.

Nothing has worked, I keep getting the same error messages described above.

I also attempted to get a refund for SimCity since I am no longer able to access the game that I paid for, but that option is also unavailable to me.

Customer support chat claims to have, "exhausted their resources," and directed me here. The poor souls working this forum are doing their best with seemingly even less resources than chat agents. When will EA provide their support teams with the resources to support their products? Clearly this issue is far reaching and impacts a number of games. 

I know EA is poorly run with little respect for their customer base - I stopped purchasing games from them years ago for that reason - but what am I to do when my favorite gaming IPs from Maxis get bought up by EA years after I purchased them?

If EA can't properly support the game they need to remove the requirement that it be launched via EA.

If they can't do that they should provide refunds.
