Unexpected error loading stl in Z-Suite 3.6, 4.0, 4.1 but not 2.11

I cannot load my STL. Gets “Unexpected error” on Z-Suite 3.6, 4.0, 4.1.

Loads ok with online STL viewer like https://www.viewstl.com, https://3dviewer.net, View STL Files Online for Free - Meshy AI and also Z-suite 2.11.

Model is exported to STL with Fusion 360.
