VRChat intermittently crashes to desktop without an error dialog when joining a populated instance of Mafia Classic.
World ID: wrld_80d828d2-ae5f-4fa5-aaaa-072b80096995
Other players have also reported crashes when entering this world, although their crash dumps have not been analyzed.
REPRODUCTION
  1. Join a populated Mafia Classic instance.
  2. The world scene loads successfully.
  3. Player/avatar initialization begins.
  4. VRChat sometimes unexpectedly closes.
Frequency: intermittent. Both empty and populated instances have also been entered successfully.
EXPECTED
The client completes initialization and enters the world.
ACTUAL
The client crashes to desktop without an error dialog.
CRASH EVIDENCE
I captured two crashes on October 18 and October 20, 2026.
Offline analysis found the same complete 22-frame native call stack in both dumps:
  • UnityPlayer.dll version: 6000.0.67.6863
  • Exception: 0xc0000005
  • Fault offset: 0xb11b2d
  • Invalid read from address 0x58, with R13 = 0
  • Call chain enters UnityEngine.Animator::Update_Injected with zero delta time: Animator.Update(0).
The final log messages in both cases concern remote avatar limb initialization. No Udon runtime exception was recorded during the failed entry.
The specific Animator, avatar or world object responsible has NOT been identified. The last avatar mentioned in the log is not a confirmed cause.
ENVIRONMENT
  • VRChat 2026.3.3p2-1921-15c4a824b2-Release
  • Windows 11, build 26200
  • Steam installation, Direct3D 11
  • NVIDIA GeForce RTX 3060 Ti, 8 GB VRAM
  • 32 GB RAM
Crash dump, full logs and detailed analysis were submitted privately through support ticket #745343.
Could you investigate the native Animator.Update(0) crash path and advise what additional diagnostic information would help identify the trigger?
