They seem to be working the same for me in v0.1.94. Make sure that the hotkeys are turned on in both the settings GEAR menu in the top left, and in the LIVE menu. If they're both on, toggle them off and then back on and see if that helps. You could also try resetting one of the hotkey keys to see if that helps. But none of the hotkey code changed so I'm not sure what might be the problem.
One other thing you could try is running vtuber kit as administrator by right clicking the exe and Run Ad Admin.
