I'm not sure what's wrong here as it works fine in GNOME and Budgie. The terminal isn't very helpful either as it only throws out a segmentation fault:
[I] ╭─vistaus@solus /run/media/vistaus/MicroSD/Apps ‹system›
╰─$ wps
/usr/bin/wps: line 38: 16397 Segmentation fault ${gInstallPath}/office6/${gApp} ${gOptExt} ${gOpt} "$@"
[I] ╭─vistaus@solus /run/media/vistaus/MicroSD/Apps ‹system›
╰─$Or is there some way to debug WPS? Anyway: if you need more info, let me know.
