[2022] New beta is unplayable?

Originally posted by Lost Latios: Every time I try to start a game or save a new race the game crashes within the beta. Without the beta the game runs just as it should and I have no issues or crashes.

Most of these problems are due to antivirus active protections conflicts. As a temporary thing to check, disable your antivirus' autoprotection. If the game runs fine after that, add Stellaris to the whitelist/exceptions of your antivirus.
