Several EA games are not launching at all

Hello, for the past two months I'm trying to get several games to launch on my pc via Steam. To get this out of the way first, this issue appears ONLY on EA games.

In the past I've been able to launch Madden NFL 19 and every F1 game released since EA took over as a publisher, as well as FIFA 22. Those games work without any problem. Other than that, FIFA 23, Madden 22 and 23 as well as GRID Legends don't launch at all. All that happens is (in case of FIFA and Madden) that the EA app opens an empty window, closes, then aborts the game launch on Steam.

I'm genuinely running out of ideas. I have tried the following list of things to fix the problem, but without any success:

• Verify game files

• Re-install Madden

• Re-install EA app

• Cleared cache locations (EA App run as admin / Steam settings)

• Uninstall EA app and install the latest Origin version (which turned out as pointless since running Madden (or any EA related game for that matter) forces you to install the EA app - which uninstalls Origin)

• Unplug every USB-device except for mouse and keyboard

• Install (and repair) Visual C++ files

• Whitelist games and EA app in Windows security

• Whitelist games and EA app in Windows firewall

• Change GPU settings in the nVidia control panel specifically to the graphics card

• Completeley turn off Windows security and firewall

• Run as admin

• Run in compability mode

• Run in windowed mode via Steam properties

• Run from install folder

• Run via Steam Big Picture Mode

• Manually install EA AntiCheat (just tried it, but turned out pointless as well since Madden seems not to use it, otherwise Madden simply doesn't show up in the AC installer)

• Disconnect bluetooth-adapter for DS5 pad

• Deactivate all Autostart programs except Windows security

• Deactivate all Game overlays (Steam / EA / GeForce Experience)

• run cmd Scan File Check Tool (which successfully completed and replaced corrupt files)

• run Avast Driver Updating Tool (which successfully updated all outdated drivers)

• Change my virtual RAM under Advanced system settings to 4096MB

I bought Madden 23 and even subscribed to EA play to figure whether it's a Madden-related problem or not. As you can tell, nothing works.

Also tried to fix the problem by contacting the phone support but - with all due respect - "waiting until the technical support is dealing with this issue" is as cheeky as it gets. This has  "wait until you can't refund and then we don't care anymore" written all over it and I am seriously annoyed getting rejected like that. I get that telephone support can just process their script and send me links for potential fixes (which I told him before that I used them, he still sent me those in Russian - the German phone support) but in every forums or the Steam reviews you can read that this is a problem from the start and Madden and FIFA have been released several months ago. To add to the links the phone support sent me: All fixing tutorials are for Origin - which is describing folders that don't even exist anymore since the games require you to install the EA app.

Please help.

Thank you in advance!
