Not working, opens default desktop mode

[MochyPei]

I installed mod correctly, and have installed BepInEx, and i tried to open with argument "--vr", and it either doesn't open in vr, or it doesn't open at all, i have in folder one exe file of game and the shortcut that BepInEx created, i tried all of this (exe file with "--vr" just opens game, shortcut with "--vr" not opens, and shortcut with "--launch --vr" / "--vr --launch" just opens game)
I have installed and opened SteamVR and connected headset.
PC: Win10 Pro, 1050TI, 8gb DDR3, FX-8300

Just by the way, other VR games work fine for me

I am having the same problem. Have you found a fix?

If you attach a log file, I can look into it.

I'm having the same problem, the game boots into the desktop launcher after installing the mod.

This was the output log from BepinEx when I launched the game:
LogOutput.log

@bananagaming-123 That's a log file from "Koikatsu Party VR", the official VR program. It looks like you either launched the wrong program or attached the wrong log file.
