Unable to open more than one osu!framework based project at the same time

[anispwyn]

when you're opening something like osu!lazer, fluXis would refuse to open and vise versa (it report STATUS_SUCCESS after closed)

for some reason, you can open Vigette and osu!lazer (or fluXis) just fine, probably because it(Vigette) is using the old version of the framework

you can watch an example video here:

tested using:
osu!lazer 2023.1231.0
fluXis Hotfix v2024.1.1

environment:
windows 11 enterprise insider preview build 26020
r5 6600h
rtx 3050ti

No. Root cause will be in here: https://github.com/TeamFluXis/fluXis/blob/5890fbe6487e3323c379a83454f935d5a0f4f346/fluXis.Desktop/Program.cs#L25-L45

fluxis instance thinks the previously opened osu! instance is the primary instance of itself rather than a completely different framework app.

The ipc port probably needs to be configurable per framework app:
