PoE2 Atlas Crash in League Only – Standard Works Fine

I have a problem when trying to open the Atlas in Path of Exile 2.
Every time I click on the Atlas icon while in a league, the game instantly crashes.
However, in Standard, I can run maps with no issues.

I already:

Reinstalled the game via Steam

Verified game files

Deleted shader and cache folders

Tried different renderers (DirectX11, Vulkan)

Created new characters in league → same crash

I can enter other players’ maps in league, but I can't open the Atlas myself

The crash first happened after completing the Mechanical Nexus (Analysis) – I didn't get the Atlas point and since then, it crashes every time

I contacted GGG through support and forums but no answer for over a week.

Looking for solutions or any way to reset Atlas state or fix this crash.
