This is probably low chip RAM, happened on AmigaBill's stream last weekend (I think he has TF1260 card too). What he did was to lower the Workbench to 4 colors or similar, to free chip RAM.
It worked for him, but the only way to make sure is to unarchive the *LHA* version onto the SD and run game.exe through the boot without startup method (there's a mini "tutorial" for that below the download links). Thanks.
Try the one in the link below, it has game.exe and also game-crunched.exe (both should work):

Ok, please try the one in the link below, I disabled the preallocate memory option, you can click on the game icon normally:

Todd, who also has a TF1260 card, succeed in getting it to run: https://x.com/ToddsNerdCave/status/1948986038535282775
Thanks for the heads up!
I also discovered that when compiled with latest version of the engine (August 10) the non-WHDLoad *LHA* version doesn't runs through Amiga shell anymore (in the boot-without-startup method to keep highest chip mem).
So, I removed the text recommending that method. But it seems to run through normal Workbench now.
As a wild guess, I'd say that some software installed in your system during startup is causing a conflict with Scorpion Engine. It'd be interesting to take a look at your startup-sequence file.
Anyway, I did another test build, now with a Scorpion Engine version from August 15, 2025 - today (link below). Earok outputs a new build of Scorpion Engine almost daily, and they tend to give different results too as things are tweaked and improved.
