Option To Build\Export For Windows Missing From The Publishing Tab

As per the title of my post, all other options to build\export the code below are available to me, but not for Windows.

Am I overlooking something simple in the settings or is it something else?

I tried logging out of the site and back in again, but that didn't fix the problem.

Thanks for your help.

init = function()
  
  list = ["10","20","30","40","50","60","70","80"]
  
end

update = function()

list.push(list.removeAt(0))

end

draw = function()

  screen.clear()
   
  screen.drawText(list[0],0,0,50,50, "#FFF")
  
end

Hi all,

Just now before opening my browser - Firefox 100.0 64 Bit - I ran BleachBit and let it do it's thing. When that was finished I opened Firefox and cleared the cache, deleted cookies etc and when I logged in to the site the option to build\export for Windows was available to me again.
