[2021] Game Crashes to Desktop When Starting/Loading a Map

It could be memory related, but it could also be something else. The easiest way for us to tell is to see the log. I recommend you make a thread on our official support forums and attach both the output_log.txt and the error.log there. Both are found in the folder the error mentions.

To easily find that folder, right-click on the game in Steam, select Properties, find the tab Local Files and click Browse. It will take you right to where the folder is created.
