See https://test.winehq.org/data/patterns.html#taskschd:scheduler

taskschd:scheduler does not crash when run on its own: it's
schtasks.exe:schtasks that causes it to crash.

The reason is that, at least when run without elevated privileges,
schtasks.exe:schtasks leaves behind the "Wine\\test" task folders created by
the call below in schtasks.c:

  register_task("wine\\test\\winetest");

These folders then interfere with taskschd:scheduler.
Not that they are mean to be deleted by the calls below but that fail with
E_ACCESSDENIED:

    ITaskFolder_DeleteFolder(root, wine_testW, 0);
    ITaskFolder_DeleteFolder(root, wineW, 0);
