big bug, game not starting. install via steam, not starting
Ideas
Thought I'd leave this here. I was having this same issue. Splash screen would load, disaapear than drop me back to the EA app. Same thing has happened in F1 23, F1 24, and WRC on this same PC. On a whim, I tried on my laptop (Framework 16) and everything worked. So I started digging into the differences.
Turns out I was running the Microsoft Global Secure Access client (it's an enterprise product, I'm a SysAdmin). There was never any indication of any sort of network issue. Packets weren't being dropped, DNS resolves, and the client never had any policy (so it was effectively off). But removing that client (which is one of the very few differences between the two systems) resolved this issue for me.
Check if you are running ANYTHING that might be proxying traffic. Your AV, a VPN client, third-party firewall, etc. My guess is that Javelin doesn't know how to handle this and it just craps out trying to hand off to the game EXE. Of course there's no logs so.........just my speculation.
