--- Comment #85 from winehq.org@ulf-gebhardt.de --- I believe to suffer from the same bug on arch and am unable to start some applications.
If I can help with info please let me know.
Currently running wine-staging 10.11
The problem seems limited to win32 programs as win64 still seem to work (Arch does no longer provide wine32 but ships with wine64 by default).
