If the problem still persists on your end, let us know in the comments section or try the fixes below.

Try the Game on a Different Server

Path of Exile 2 - Load the Game on a Different Server.png

If you’re encountering this issue while loading a character that's currently in a town, try switching to a different server from the login screen. This forces the game to load a new instance of the town, which can bypass the one causing the crash.

Load a New Instance of a Zone

Path of Exile 2 - New Instance

If you repeatedly encounter this error when loading a specific zone, the game may be attempting to load the same instance containing the issue, causing a crash. You can bypass this by creating a new instance of the zone. Hold Ctrl before clicking on the zone to open a menu that allows you to generate a fresh server instance.

Restart the Game

Since this error appears to be a server-side issue, restarting the game and logging in back again should resolve the problem when entering a new zone. This should also apply any of the latest Hotfixes that the developers release to fix these kinds of issues.

Path of Exile 2 - Game Crashes While Loading a New Zone

This error occurs when attempting to load a new zone, causing the game to crash. It has been a common issue, especially during the launch of the Dawn of the Hunt update launch. Since it is a server-side problem, the resolution largely depends on developer-side fixes and server stability.
