The game crashes after I complete Northshire Abbey/Red Ridge Mountains

[paowoww]

After I complete the missions, the game freezes for a few seconds then displays an error message saying Stratagus failed to load game data. Is this a problem with using an illegitimate WAR file, operating system, or can it be a hardware issue? I'm on Windows 11 with an Intel Evo i7 with integrated graphics.

The game crashes when I complete Northshire Abbey. I do not know about crash with Red Ridge Mountains, I did not try it.

OS: Linux Mint 21.2 x86_64
I got the game from GOG.

Error text:
"Stratagus failed to load game data. If you just launched the game without any arguments, this may indicate a bug with the extraction process. Please report this on https://github.com/Wargus/stratagus/issues/new, and please give details, including: operating system, installation path, username, kind of source CD. If you got an error message about the extraction command failing, please try to run it in a console and post the output to the issue. A common problem is symbols in the path for the installation, the game data path, or the username (like an ampersand or exclamation mark). Try changing these. Try also to remove the folder /home/technik/.stratagus/data.War1gus and try the extraction again."

Edit:
I forgot to mention, that i already tried "to remove the folder /home/technik/.stratagus/data.War1gus and try the extraction again."
