Can't connect iPad as a second monitor or for Universal Control

All work well before I did a full reset of my MacbookPro M2 Max and my iPad Pro.

But now it's impossible to use Universal Control or to use iPad as a second monitor. I can see it on the monitor settings, but when I clic I have an error... It's very annoying. I turn off every thing, like bluetooth, I reset bluetooth too. I reinstall every thing but still nothing work fine.

An Idea to explore ? Thanks a lot
