[2019] Can't Play Anymore

Would you be able to show me the full callstack? You'll be able to find it in this folder:

SteamLibrary\steamapps\common\ATLAS\ShooterGame\Saved\Logs

You'll be looking for a .crashstack file, it opens in notepad. You can paste the contents at www.paste.bin.com / here directly / upload it as an attachment.
