`hs.spaces.removeSpace` fails

[acheronfail]

I've noticed that hs.spaces.removeSpace doesn't work for me, some details:

• macOS 14.5
• Hammerspoon 0.9.100

Here's an easy way to reproduce the error:

-- this is run directly in the hammerspoon console (ensure you have more than one space):
> for _, spaces in pairs(hs.spaces.allSpaces()) do
  hs.spaces.gotoSpace(spaces[1])
  hs.spaces.removeSpace(spaces[2])
end
-- ...merspoon.app/Contents/Resources/extensions/hs/spaces.lua:882: attempt to index a nil value (local 'child')
-- stack traceback:
-- 	...merspoon.app/Contents/Resources/extensions/hs/spaces.lua:882: in function 'hs.spaces.removeSpace'
-- 	[string "for _, spaces in pairs(hs.spaces.allSpaces())..."]:3: in main chunk
-- 	[C]: in function 'xpcall'
-- 	...poon.app/Contents/Resources/extensions/hs/_coresetup.lua:525: in function <...poon.app/Contents/Resources/extensions/hs/_coresetup.lua:505>

I've tried increasing hs.spaces.MCwaitTime, but I have a sneaking suspicion that this has something to do with #3636, perhaps something was changed in macOS 14.5?

FWIW, I've also checked out and built #3638, and the issue also occurs with that version, too. 😢

Also experiencing the same issue after upgrading to latest MacOS. Scripts did not change, hammerspoon version same as before. Something must have changed in MacOS itself.
