Yes, that's because you have only 8GB of RAM and it's desirable to have at least 12 GB of RAM at this point of game development.
Try installing game to SSD, increasing paging file (set pagefile on your system/game drive to at least 16GB), decrease graphic settings and don't forget to close any unnecessary programs running in background, before starting BSGlauncher. Also turn on new options in game settings - "RAM auto-clearing" and "Use only physical cores" option (it will reduce overall freezes and stuttering). Also overclocking your CPU (Ryzen) might cause crashes/disconnects in game, so if that's the case then you need to return to default/factory settings.
