Output Arcade doesn't work in Cubase, but it works standalone

when I load Arcade in Cubase it stucks in init custom kit. It perceive my keyboard’s input but I can’t click something else like settings, browse whatever. But when I load it standalone it works fine. I’ve been searched about this issue such a long time. I deleted Arcade clearly and reinstall, checked my window and Cubase’s Hidpi settings etc. But I can’t fix this troubleshoot with whole bunch of things.

Please help me. How can I solve this problem?
Maybe I lost something in solutions what I did?
I’m using Cubase 10.5, Windows 10
