Thanks to you! You helped so much. Looks like i'm almost fix everything. There is only one last thing. So in built and editor now everything works great except one thing - for some reason i can't press response buttons with mouse. Only keyboard
Before i was able to do it with mouse. NewInputMode is enabled.
Someone else fixed a similar issue today. See this post. Make sure you're disabling UHFPS Kit's mouse control while in conversations. See 07:00 of the Interaction Tutorial video if you need more info.
Quick update on my issue.
So I tried almost everything on internet to fix UHFPS+DS in my situation. I tried all your recommendations and in other topics but no luck.
FINALLY. For some reason, everything works only when i disable Canvas that UHFPS kit creates. So this is my solution. I disable Canvas UHFSPS bн Dialogue OnConverstion Event. Maybe there is some more elegant ways. But in my case it's 100%.
