black screen with shootyourscreen and screen grabber plugins

Need help with plugin Screen graber 2.5 for VU + Zero4K. The same plugin on the receiver VU solo SE V2 gave jpg. neatly, and with VU zero 4K, a totally black picture, although I get a notification that the screenshoot is done properly. The question is ... should you install another plug-in or someone may have a properly configured plug-in to work. Thank you in advance to everyone ...
