As of the latest OpenDeck update (2.7.1) the VTube Studio Stream Deck plugin no longer works on Arch. It's just crashing. I've tried both the 3.x and 2.0.0 version of the plugin, the Flatpak version of OpenDeck, reinstalling .NET and wine-mono, the plugin still refuses to work.
Attached is the plugin log and the Wine backtrace log.
