If you receive an error message stating the game has run out of memory whilst the game is loading, it may mean you save file is corrupted please read – https://community.sigames.com/faq/football-manager-2020/239_technical-support/244_pc/my-save-game-no-longer-loads-r885/
If you receive an out of memory message at any point of the game, if you're running any custom graphics/logos/skins or any other add-ons, try removing them for the time-being and see if you encounter the same issue.
If it no longer crashes after this, it may be an issue with a specific addition, so we'd recommend slowly adding them back in parts to see if there's one specific thing that causes it. If it still crashes without any additions, please move on to the next suggestion.
Delete Cache and Preferences
Verify Game Files
If none of the above helps, we'd recommend checking your virtual memory and making sure it's not to low. Details on how to do this here - https://www.pcworld.com/article/2840886/if-windows-virtual-memory-is-too-low-you-can-increase-it-but-there-are-trade-offs.html
If you’re still having issues you cannot resolve, please contact submit a support ticket.
