The CTDs continue when the simulator is loading / activating packages. The only difference is that when I delete all caches, the process continues, but before finishing the loading it crashes to desktop.
I have an AMD 5700X with a 6750 XT (12 GB). I am using Windows 11 fully updated and the latest AMD driver.
I have tried removing the Community folder and deleting the caches, but the problem still persists.
I had to leave the beta again, just like with the previous build. I also reinstalled the driver after cleaning everything with AMD Cleanup Utility, but the problem still persists.
I am currently using driver version 26.2.2, which worked without any issues before. In addition, everything works perfectly in SU4 and also in SU5 build 1.7.9.0. The problem only appears in the newer SU5 builds.
After leaving the beta and returning to SU4 everything works perfectly again.
I have also tested older driver versions, but the problem remains the same.
The crash log it generates is the following:

CTD during startup (BOOT_PRESSSTART) – Exception 0xC0000005 – amdxc64.pdb
Problem Description
The simulator suffers a Crash to Desktop (CTD) during the initial loading screen, specifically during the “Press Start” phase. The crash occurs approximately 34–36 seconds after launching the application.
Crash Log Technical Details
• Exception Code: 0xC0000005 (Access Violation).
• Faulting Module: amdxc64.pdb (AMD Graphics Driver).
• Simulator State: MainState:BOOT SubState:BOOT_PRESSSTART.
• Build Version: 1.7.11.0.
• Failure Purpose: GUI::CVpRootInGameData.
System Specifications
• CPU: AMD Ryzen 7 5700X 8-Core Processor.
• GPU: AMD Radeon RX 6750 XT.
• Driver Version: 26.2.2.
• RAM: 32 GB (Total System Memory: 34,278 MB).
• OS: Windows 11 (IsMSIXVC: true).
• Graphics API: DirectX 12 Enabled.
Hardware & Rendering Context
• Video Memory Budget: 12,031 MB.
• HWS (Hardware Scheduling): Disabled (HWS_Enabled=0).
The raw callstack indicates the error is triggered within the AMD driver’s core execution while the sim is initializing the UI root data. This suggests a memory access conflict between the DX12 renderer and the specific driver version being used.
