Black screen captured

Is service and daemon different things? Without root active on NOX there's just a "Media projection" option. With root turned on there's "root" option and it works, but those system toasts about root access hide some buttons I should click to, so I'm looking for method which doesn't require root access.
Also, I've headed up with some strange behavior - some popup window appears after I use waitClick method. It takes about 3 second to appear and then next waitClick method run, but it doesn't wait at all, even if say it to wait 100 seconds. You could check code here, line 63 always crashing. Maybe, this is because of "snapshot" at line 52, but I had to add it, because script didn't update picture at all. When some of checks (53-54 lines) should be passed (check in different single-run script) in this endless cycle it didn't without "snapshot" call.

I've installed daemon and now using it. But my 2nd problem still happens. Should I create new thread?

Here is the screen and error:

I'm looking for  in correct area, but script doesn't wait after first waitClick

I have to wait this image. I've cut some code just to test region and image inside it:

-- ========== Settings ================

Settings:setCompareDimension(true, 960)

Settings:setScriptDimension(true, 960)

Settings:set("MinSimilarity", 0.75)

Settings:snapSet("OutputCaptureImg", true)

regions = {

   defeatedReady = Region(241, 172, 223, 77),

   drop = Region(574, 43, 153, 153),

   dropAd = Region(485, 358, 224, 78),

   energy = Region(137, 143, 141, 137),

   energyBuy = Region(390, 392, 178, 68),

   energyClose = Region(820, 44, 100, 92),

   energyConfirm = Region(402, 352, 158, 68),

   label = Region(340, 173, 292, 93),

   replay = Region(245, 269, 231, 84),

   resurrect = Region(484, 262, 232, 95),

   start = Region(772, 412, 188, 128)

}

-- ==========  main program ===========

setHighlightStyle(0xff8fff00, false)

regions["drop"]:highlight()

setHighlightStyle(0xff8fff00, true)

local victoryRes = regions["drop"]:exists("close.png", 2)

local m = regions["drop"]:wait("close.png", 7)

if (victoryRes and m) then

m:highlight()

   toast('exist')

else

   toast('not exist')

end

wait(3)
This code is works correctly and highlight both region and found image, but it doesn't work in code I've pasted before after 2 waitClick's in a row

Also, I've got the same error when replaced "region:waitClick" with "region:wait + region:click". And "region:existsClick" is not an option, because I know 100% that this popup appears.
