TS4 broken under macOS 14 Sonoma

Had a bit of a brain fart this morning and installed Sonoma (macOS 14). If you're considering updating DON'T - it breaks the game. It gets as far as the splash screen and then just beach-balls endlessly.

I have everything bar Horse Ranch and a few kits. I have no mods or CC installed. Running on a M1 Max MBP (64GB/4TB). I have restarted my Mac in safe mode, didn't help. It doesn't crash, so I can't glean anything from a 'send to Apple' report. I left it for about 10 minutes to see if it would resolve, obviously it didn't. 

I realise that Mac players are kind of a second thought when it comes to EA, but we do exist. 

Is this a known issue...? I don't have a fast enough connection to be able to uninstall and reinstall everything again. I can't give you any more info than this, it refuses to load past the TS4 splash-screen, I don't get any music either. 

If you have got it to load successfully under Sonoma on a M1 Max then please let me know how you did it. 

Thank you
