I think one workaround worth trying is to launch 1.85 and select the SPD tab, then launch 1.86 - somehow this helps to unbug the SPD tab on some platforms You can then close 1.85 and take your screenshot.
The main hwbot.org site is down with the usual "the HWBOT engine is currently overloaded" which happens quite a bit when it's busy but unusually today it's stayed like that for at least 3 or 4 hrs. What's going on?
