HOLOLENS GEN1 UNITY 2022

Hi! 

I'm using hololens 1 with unity 2022 and the MRTK version 2.8.2. When I am in the project in unity everything is ok,
 it exports the appx file
 fine but when I add it from windows device portal and start there is a window, it is not even
 in full screen, it does not start with the unity logo and it is all black! Does anyone know why?
I have been investigating for two weeks now, I have no knowledge of programming and I know very little about unity for that reason. but hey, some help would be good, thanks!
PS: I have windows 11 HOME
