Affinity Designer 2 crashes on Windows 11 ARM (Snapdragon X Elite) during outline conversion

[illustoria]

【App Info】  
- App: Affinity Designer 2 (Microsoft Store version)  
- Version: 2.6.0.3134

【System Info】  
- OS: Windows 11 Home ARM64 (Version 24H2, Build 26100.3624)  
- CPU: Snapdragon X Elite (X1E-78-100)  
- RAM: 16GB  
- GPU: Qualcomm Adreno X1-85

【Issue Summary】  
Affinity Designer crashes frequently on my device. The most recent crash occurred when I was performing "Convert to Curves" (Outline stroke) on vector objects. The app closed instantly without any error message.

【Settings Info】  
- Hardware acceleration (OpenCL): OFF  
- Display quality: Nearest Neighbour (Fastest)  
- Auto-save interval: 300 seconds  
- Undo limit: 300  
- Renderer: Default (Qualcomm Adreno X1-85)

【Event Viewer Crash Log】  
Application: Designer.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException
at Serif.Interop.Persona.NewDocumentDialogDataSource+FileCollection.GetCount()
at Serif.Interop.Persona.NewDocumentDialogDataSource.OnSelectedFolderChanged()
at Serif.Interop.Persona.NewDocumentDialogDataSource.OnAuthStatusChanged(...)
at Serif.Interop.Persona.Services.InteropService.OnCloudSvcsAuthStatusChanged(...)
at Serif.Interop.Persona.Services.InteropService.HandleNotification(...)
at Serif.Interop.Persona.Services.InteropService.OnNotify(...)

【Additional Notes】  
I was not creating a new document when the crash occurred; it happened during an outline conversion. However, the log refers to `NewDocumentDialogDataSource`, which might be an internal function related to auto-save or file handling.  

I would appreciate any insight from the Affinity team, and I'm also curious if full ARM64 native optimization for Snapdragon X Elite is currently under development or planned.  

Please let me know if you need more diagnostic info or a crash dump.

@illustoria Sorry for the delay.

We could do with a complete copy of the crash reports from your system for checking.

We do have native ARM64 support, this was added in our 2.5 release, see here for more information.

Same system, same problem. The program loads super quick but just like above, it doesn't stay open. Some of the crashe 

s seem random but a few, when I try to use the ai tools ⚙, crash every time. I will get a log and post here
