Hello. I am reporting a persistent and critical instability issue with the Second Life Viewer (this occurs on both the Official Linden Lab Viewer and Firestorm Viewer). The application experiences an immediate crash upon the very first launch after a system boot. The Viewer then runs completely stable on the second attempt without any system changes. This bug is consistently reproducible across different Viewer versions. This issue occurs on the following system configuration:

Operating System : Windows 11 Pro 64-bit

Processor AMD Ryzen 5 7600

Graphics Card : NVIDIA GeForce RTX 4060

NVIDIA Driver Version: 555.99

System RAM: 32 GB DDR5

Windows Power Plan: AMD Ryzen Balanced.

To achieve any kind of stability upon initial launch, two specific workarounds must be applied simultaneously:

VSync Must Be Disabled: Vertical Sync (VSync) must be explicitly DISABLED within the NVIDIA Control Panel for the Viewer application.

Run as Administrator: The Viewer client must always be launched with Administrator privileges.

All standard and advanced troubleshooting methods have been exhausted. The following critical tests confirm the issue is software-based:

Hardware Stability Confirmed: Power Supply Unit (PSU) and GPU stability have been verified. The computer successfully passed a full 15-minute GPU stress test using FurMark (running at 100% usage, even with VSync on) without any system shutdown or crash. This rules out hardware failure (PSU/Overheating).

Software Scope: The problem is confirmed to occur on the Official SL Viewer, Firestorm Viewer, and older Firestorm versions.

Other Steps: All drivers/OS are updated, cache has been cleared multiple times, and various graphics debug settings (VRAM detection overrides) have been attempted without success.The issue appears to be rooted in the Viewer's core initialization process (likely VRAM allocation or system file access) during its initial cold start on this specific hardware configuration.I have included the Crash Logs from a failed first launch attempt. Please use this information, particularly the log files, to diagnose why the core Viewer code is unstable upon initial launch on a system running the NVIDIA RTX 4060. I didnt do picture. because dont show me only just close me all game and computer. i have that from one week, before did work normal and without problems. A rigorous, clean reinstallation of the NVIDIA drivers (using DDU) has been performed. Following this process, the complete computer shutdown issue has been resolved, but the game still crashes on the first launch attempt. I must use the workaround (Run as Administrator + VSync OFF) for stable operation. This definitively confirms that the bug lies deep within the Viewer's core code and requires your intervention. With close Vsync and I'm starting as an administrator game close too. close me again but after 3 h. i did try too take off my all avatar and wear old from firestorm but is same. i send one picture what show me after close game.
