I've been trying to launch multiple instances of Celeste using Nucleus to play locally on my 2 screens monitor with my brother, but every time the second instance try to launch, I get this errro log:

==========================================

Ver 1.4.0.0-fna [Everest: 6194-azure-5adc0-stable]
03/30/2026 23:08:20
System.Exception: FMOD Failed: ERR_NOTREADY (Operation could not be performed because specified sound/DSP connection is not ready.)

Anything that might be helpful to sole it ?

Turns out Fmod is disable when i open the game manually, but the instances have it enabled for Everest

i know, dont't understand it either

#

saves and settings are in the same folder in celeste so maybe it's using settings from in that folder instead?

#

if you want to try manually changing it, it should be the LaunchWithFMODLiveUpdate setting in settings.celeste
