QXcbConnection: Could not connect to display Aborted (core dumped)

After latest apt update on Linux mint all snap applications are getting the following error:

QXcbConnection: Could not connect to display 
Aborted (core dumped)

Operating System: Linux Mint 19.3
Kernel: Linux 5.0.0-32-generic
snapd is already the newest version (2.47.1+18.04)

Is this happening for anyone else?
