@combinatorial I'm not seeing any unusual behaviour with this. I suspect there is a hotkey conflict or issue on your Mac causing something to still have focus (e.g. Spotlight). You could try one of the two following things:
Change Alfred's hotkey back to the default alt+space and see if the behaviour is normal
Check the cmd+space troubleshooting to make all listed macOS features are disassociated with cmd+space: https://www.alfredapp.com/help/troubleshooting/cmd-space/
