Clipboard Not Working on macOS 10.14

So I tried to used RightQR for the first time since "upgrading" to macOS 10.14 after holding out for so long. The clipboard does not work. This is a mission critical failure as there is no other method to extract the scan data:

clipboard failure macos 10.14

After a reboot I will post a bug at bug at http://bugreport.apple.com if it still isn't going. Hopefully my computer will behave.

I also do not like some changes to the way the keyboard input works. Especially regarding the combo: Command-option-control-Equals and Command-option with -=  (magnifier). It interferes with the app "Spectacle" which I use to organise my windows. Dark mode is freaking awesome though. And I find that Finder and Activity Monitor crash much more on Mojave, with more reboots and logout/ins.

It's no biggy but I there is a subtle difference depending on the exact order the keys go down on the board and I find it annoying to think to do it the right way (all at once fast not progressively).

PS bring back the 3.5mm" jack.

Bug report:

After copying to clipboard scan data from Right QR ( Version 1.2 (1.2) Copyright © 2012-2013 Ripe Apps Inc. All rights reserved. Last modified: 1 August 2017 at 10:09 PM ) I am unable to paste.

Pasting causes no text to appear.

I can see successful copy pastings of text content in CopyClip (v 1.9.2 2019) so I know other apps can still copy paste text! Perhaps CopyClip is interfering, as I do not recall running it under 10.13 (I may have done but that app mod date is 7/7/2019 which I reckon was after I installed Mojave). Potentially I should troubleshoot out that variable but I do not feel this is something I should have to do, and the clipboard is super important so i don't wantApple ruining the OS in coming releases, something I feel is highly likely with the announcement of dropping support for x86 32 bit binaries (why?).
