Razer Blackwidow Chroma V2 locking up

Hi All!
I’ve been trying out SignalRGB and am very impressed. One issue though is preventing me from becoming a user… Whenever I go out to my Windows 11 lock screen and try to switch users, my Razer Blackwidow Chroma V2 keyboard locks up and will not respond to key presses.
I tried to disable all keyboard related macro functions, low level hooks, but to no avail. The only fix is to pull the USB plug and plug it back in. Then the keyboard becomes responsive again.
Any idea how I can fix this? I have a couple of people on this PC switching, and this makes SignalRGB unusable…

I also checked logs - in case helpful. they are full of lines that look like this - in case useful…
