Exception error on computer shutdown

[pixelvertice]

Every time I shut down or restart my PC sometimes Streamdeck-Vtubestudio process throws an error message, despite I don't have Vtube Studio running. Here's what I see at Event Viewer

Application: streamdeck-vtubestudio.exe
CoreCLR Version: 5.0.1722.21314
.NET Version: 5.0.17
Description: The process was terminated due to an unhandled exception.

Thanks for the information, what this would be related to is the StreamDeck connection itself isn't actually closing in the "proper" way on a PC shutdown.

I will have a look at some ways this can be handled in a more graceful manner to not generate the error log.

untested as I have yet to try it on my own side,but https://github.com/Cazzar/VTubeStudio-StreamDeck/releases/tag/2.0.1 may fix the issue, will be testing it within the next 24-48 hours locally

https://github.com/Cazzar/VTubeStudio-StreamDeck/releases/tag/2.0.2 has fixed this issue, let me know if there are any further issues.

I have monitored locally after fixing this issue and it is not showing any errors on shutdown/force closure of the Streamdeck host application.
