I am using Ubuntu 21.04 and I just installed ElectronPlayer but it is not launching. So, I tried to launch it with terminal by typing electronplayer but it gave me error

gtk-warning **: 01:10:18.304: cannot open display: :0

And if I do sudo electronplayer, I get

mkdir: cannot create directory '/run/user/0': Permission denied

Try updating your snap package.

To update snap package follow these steps from Zygmunt's answer on How can I update all Snap packages?

sudo snap refresh 
Will do this. It is part of snapd 2.0.8, which landed 2016-06-13 in
xenial-updates.
snap refresh --list
Only lists the updates without refreshing the packages.
snap info <snap name>
Can show which versions are available for a particular package.
