Supernote device does not connect and error when closing

[amdemas]

I am on Windows 11 and the device does not show as connected when running the app. Also when closing I get the following error.

Hello @amdemas, I do not have a system running Windows 11, so it took me a couple of days until I was able to install Windows 11 under VMWare Workstation 17 Player.

Tested SDC with the following configuration:

• Windows 11 version 22H2 (OS Build 22621.1413)
• .NET 6 desktop: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.16-windows-x64-installer?cid=getdotnetcore
• Latest SDC release: https://github.com/nelinory/SupernoteDesktopClient/releases/tag/v0.2.8514

Unfortunately I am not able to reproduce the error you are getting. On my Windows 11 test machine the SDC works as expected including the detection of Supernote device and ability to sync all notes. No errors were received under the multiple test scenarios executed.

A new version will be released next week, which have build in diagnostic mode with more detailed logging. Hopefully it helps us figuring out the issue you are having.

@nelinory I will try the version listed and let you know.

@nelinory That version worked! I do not get the error when closing, and the device shows as connected. Thank you!
