I am running macOS 10.14.5 and using alfred from sometime now
I have not faced this before but it happened unexpectedly and I am not able to fix it.
whene I press the key combination for alfred it does not appear but i see it generates crash log in /Library/Logs/DiagnosticReports/
I have tried uninstalling with appcleaner several times, re installed but nothing works, even I am not able to launch the Alfred Preference app from the /Applications/Alfred 4.app/Contents/Preferences/Alfred Preferences.app
Please help me to fix it, I am attaching crash logs. here: https://www.dropbox.com/s/rdgttit5l6k3wh3/Alfred_2019-07-18-184316_iMac.crash?dl=0
