Game crashes when entering the match

For this solution I used 1048576 or 8GB of virtual memory as it's the becoming the new default on many Linux Systems. To permanently change your virtual memory limit you must edit a system file that you will need escalated privileges for. We will be editing sysctl.conf but depending on your system's configuration you might need to change a different file.

Open the file via the editor of your choice with sudo. For example sudo nano /etc/sysctl.conf and add the line vm.max_map_count=1048576 to the bottom of the file
