it seems that Tumbleweed offers a broken version of FreeCAD
that fails to open existing FreeCAD files
i can confirm the problem reported in detail
by another user on the FreeCAD forum:
https://forum.freecadweb.org/viewtopic.php?p=499618
how to report the issue to the openSUSE team
?
i failed to access
https://bugzilla.opensuse.org/
“The server encountered an internal error and was unable to complete your request. Please contact SUSE customer support.”
THANKS
