Expected result

Steam client remains stable and the summoning process completes successfully.

Actual result

Steam client crashes during the summoning process on both players' systems.

I think something similar is happening in Elden Ring Nightreign - The game and steam client both crash upon a player joining the lobby. Unsure why it seems to be only with fromsoft games though.

NNTMan 2025-12-29 github

Confirmed fixed in Steam client version 1766962227 (public beta).

Tested co-op and invasion in Dark Souls III and Elden Ring —
the Steam client no longer crashes on either side during summoning.

Nothing extracted yet.
