I'm trying to run TR3: TLA on my Ryzen 5 3600 + RX 6600 XT, Windows 10.

I've already set MMX 0 in config.txt, without it the game will crash when entering main menu (this is because the game attempts to execute 3DNow! instructions, which are not supported on Ryzen CPUs).

But now the game is crashing when I select "new game", or try to load a savegame from another PC.
Interestingly, Lara's Home works fine.

I tried various resolutions, compatibility settings (e.g. for Windows 95), dgVoodoo, even software mode - nothing seems to work. The game will crash to desktop with no error messages.

On a Core 2 Quad Q9550 + HD7850 everything works fine.

EDIT: on i7-9750H with GTX 1650 the game runs fine as well...
