Hello. My unity keeps crashing whenever the VRC SDK base is added.

This is the error: [ Could not allocate memory: System out of memory!

Trying to allocate: 1674037094537B with 16 alignment. MemoryLabel: TempOverflow

Allocation happened at: Line:525 in C:\build\output\unity\unity\Runtime\Core\Containers\StringStorageDefault.h

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&) ]

I have confirmed hardware and virtual ram/memory is not faulty as older unity projects open and run, but any new projects almost immediately crash with the same above error.

I have narrowed down the issue as coming from the XR plugins (openXR, OculusXR, XR plug in manager) that I have failed to remove or disable as unity auto reinstalls them and then crashes immediately when installed.

I have confirmed this is the potential source as I ran a blank unity project without the SDK and the installed the XR manager/plugins, causing an instant crash.

How do I remedy this or is there an SDK version that does not install or use the XR plugin ins as i don’t test my models in VR within unity itself.

Latest VRC SDK as of 7/30/2026
