Dualsphysics executables not valid error #266

Hi,
The configuration is:

• FreeCAD 1.1.3 AppImage
• DesignSphysics 0.8.2
• Other FreeCAD AddOns installed but not loaded
• OS is Debian 13 KDE

The DualSPHysics binaries have been placed inside the correct folder (./.local/share/FreeCAD/v1-1/Mod/DesignSPHysics/dualsphysics/bin) but the Setup Plugin still gives the same error about all the executables that they're not valid.

The proper permissions have been issued (executable flag) even for all users but the error still persists.
The simulation works anyway but the "Special" button won't work due to this issue.
How can we fix this?

EDIT: This doesn't happen on a Windows 11 Pro Install (dual boot with the same set of packages and same DesignSPHysics version)
