No, still Intel version launching it manually. Already tried it.
I suspect some setting/cache being responsible for that. I think the original version, when it came, out was Intel only and that's saved somewhere. A few hours later the first patch came out. I'll try to remove the game completely including all involved files and install from scratch whenever I find the time for it. I'm not alone though, found some Reddit and Steam posts complaining about it a while ago.
Not that something is wrong with the Intel version. The game isn't demanding and it worked absolutely fine for me when I played through it on my M1 Max.
