[PC] Repeated crash during world entry — Animator.Update(0), UnityPlayer.dll +0xb11b2d
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 Join a populated Mafia Classic instance. The world scene loads successfully. Player/avatar initialization begins. 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?

Line Quality of Frosted Scribe Ice Pen Degraded
The Frosted Scribe ice pen is one of my favorite paid items since its release in winter. I use it often when a world I visit doesn't have a pen solution in place already. I find it very useful, and to my perspective (as a Local user of the item) I unfortunately did not know MOST of what I was writing was degraded or illegible when using the pen. It seems like since the update to the Frosted Scribe ice pen to fix the synchronization issues (referenced here https://feedback.vrchat.com/bug-reports/p/synchronization-issues-with-frosted-scribe ) the line quality is now different enough to seem to have changed for the worse. The synchronization seems to depend on the IK of the remote user to draw, so if someone is not looking directly at you the entire time you are using the pen, anything you have tried to do with it greatly suffers. Even if you are being looked at directly, if you draw or write a stroke a bit too fast, the lines may also greatly suffer. Also sadly because the pen itself has a time limit, one who uses it has motivation to get everything out quickly before the pen begins to un-draw its lines. So there is motivation to draw or write fast, but Locally you do not know what you have made becomes illegible or incomplete to other Remote users until they show you a print and ask you what you were trying to do. Additionally, the line quality suffers from an odd bug. The line does not seem to stay still at the top and bottom of the pen lines. This can be recreated by anyone with the Frosted Scribe ice pen item by making an up and down close together zigzag without ending the pen stroke. Example: like WWWWWWW or /\/\/\/\/\/\/\/ These sorts of motions are commonly used to fill in areas of a drawing, and you do not expect the pen line to move. To see the unexpected behavior look left and right with your head, or slowly move/strafe your body left and right, the top and the bottom peaks of the pen line will twirl, flip, and move at the peaks and bottoms. This movement seems like a bug rather than a feature of the pen, and is not desired behavior as a pen-user. I really like the Frosted Scribe, and I appreciate that the synchronization has since been fixed so writing with it can be seen again by others at all. But this more recent bug for the line quality seems to have been introduced since the last update has also greatly degraded its original ability. Attached is an image collage of Local use, Remote use when being watched the whole time, and Remote use when not looking. This test can be re-created with 3 people with the same or very similar results each time, sometimes even worse when looking away. As you can see remote use becomes illegible FAST even when being looked at the whole time, that's not good :( Images demonstrated from top to bottom: A drawing, some simple shapes and a filled in area with "Hello", and the sentence "The quick brown fox jumps over the lazy dog"
