Describe the bug
When VRCX is launched while VRChat in VR mode is running (I have not tested for desktop mode yet), it will crash immediately after loading into the UI. The issue does not occur if VRChat is closed.

To Reproduce
Steps to reproduce the behavior:

Open VRChat in VR mode and have it running in the background.
Launch VRCX.
Observe it loads the UI for a while before it crashes.

Expected behavior
VRCX should be able to launch normally even when VRChat is running.

Screenshots
These are what I discovered in Windows Event Viewer when checking the Application menu in Windows Logs:

What version you are running
Version 2025.11.16
