Pycharm on ubuntu stuck on startup and never loads UI

Problem:

While running 'pycharm-professional' remotely via SSH and X-Server, the startup process never finishes and no X window appears locally. It hangs without throwing any errors. The x-server is verified to work by running other UI applications like xterm.

Server: Ubuntu 18.04 LTS

Version: 2020.2.3 (professional)

Installation: Installed pycharm-professional via snap (directions from website)

Remote SSH / XServer running via MobaXterm

Terminal Output:

myuser@myserver:~$ pycharm-professional
