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.

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

When i press "Build & Test" button with number of clients 2 or more, Easy Anti-Cheat says that it does not allow to start more that one instance of it per game, launching only 1 VRChat client.

When adding Gesture Manager to a Unity 2022 project, VCC warns that the SDK will be downgraded from the new beta SDK to 3.4.2.

Apologies if this is in the wrong location. The newest Package Resolver Tool 0.1.27 does not work on Unity 2019 due to a change in VRC.PackageManagement.Resolver.Resolver.ForceRefresh. 0.1.27 is being offered to Unity 2019 projects even if "Show Pre-Release Packages" is disabled. The previous version 0.1.26 works just fine. Perhaps 0.1.27 should be marked incompatible with 2019 in some way, or the change in ForceRefresh should be gated behind a unity version define check.

In order to recreate this issue, you must update your SDK in Creator Companion with Unity completely closed. Close Unity. Update Avatars SDK from 3.5.0 to 3.5.1. Launch Unity. Go to a VRCPhysBone component or similar. In some situations, an Error will be thrown and the UI Instance will not load correctly (see screenshots attached). In this example, VRCPhysBone is not loading correctly. This is probably an instance of Unity failing to load DLLs correctly. Since the VRC Phys Bone component is loaded from VRC.SDK3.Dynamics.Phys Bone.dll , Unity failed to load the instance of it correctly. To get around this, you must manually click VRChat SDK -> Reload SDK in order to force Unity to recompile all the SDK's Scripts and DLLs. If successful, this problem will disappear and everything goes back to normal.

Hello, last month I have updated my avatar project from 2019.4.31f1 to 2022.3.6f1, it was without issues and I did some avatar updates, uploaded and it was fine. Today I opened the project, got an error already while opening and after that I got this error messages in Unity. I get the same error even if I create completely new 2022 avatar project using VRC companion. Old 2019 projects are working, 2022 not. After opening 2022 project, I have only one option in VRC SDK menu "reload SDK" but this button is not doing anything. Is this some issue related to latest updates? I had VRC SDK 3.5.1 and I got this error, so I updated it to 3.5.2 but it's still the same. Can you please check? Thanks

SDK Version: 3.6.0 Unity Version: 2022.3.22f1 Issue: When upgrading my world projects SDK to the newest available one via VCC (and upgrading the unity version as well), my project receives this strange MIssingReferenceException error. This error prevents me from building and uploading my project. I attempted to find the issue in the code, but I could not isolate anything. I've tried to remove the SDK via VCC and reinstall it, but that solution did not work. Previously, I had fixed this issue by downgrading a SDK version, but that solution also no longer applies. Also, this specific error is not visible via the SDK panel, rather the SDK panel lacks any information on what causes it to not let me build. However, I can 'Build and Upload' and it will throw the mentioned error.

Just appeared today, when I was opening the project with VCC normally, and the builder panel is not working, only one specific project appears like this, but with opening other projects for comparison, those other project doesn't appear to have the same problem like this, and I can't really find the reason that cause this specific project to malfunction, I mean like I can just open it last time without any problem, but no more today. Please help. https://gist.github.com/xiaoxi654/966f38b9821b184888708d79764544c2

for EasyEventEditor.cs:262 I had to modify to: if (enableOverride && drawerTypeMap!=null && drawerTypeMap.FieldType!=null) on a fresh install (Version that came with the current VRCSDK). It was constantly throwing a NullObjectException on 264 and breaks the 3D view for editor. I know this is UdonSharp, but it still happened only in the current SDK (Worlds-3.6.1)
