Question Portrait (vertical) mode not working anymore on last Unity versions (on PC)

Hello, some time ago I've developed a project for a vertical monitor (1080x1920) with Unity 2020.3
I've been working in Game mode with 1080x1920 resolution, and to release the application (.exe) for the vertical monitor in fullscreen, all I had to do was to set "Fullscreen Mode" --> "Fullscreen Window" in the Project Settings.


Everything was fine, but now I had to implement a new plugin and switch to Unity 2022.1
Now, with the very same settings (I've just opened the project in the new Unity version), the application does show in "fullscreen" but it's almost a square, with a lot of black space over and under.


I did several test:
- With Unity 2021.2
- with "Exclusive Fullscreen" mode
- forcing the resolution to 1080x1920
Nothing! The result is more or less the same. Does not work
Is it a (huge) new Unity bug?

Any help would be much appreciated, because I'me really in a hurry and I don't know what to do...
Many thanks!

 

*** SOLVED ***
It's a unity Bug

After many hours I've found a solution.
You have to go to Windows Registry, and delete "HKCU\Software\ExampleCompanyName\ExampleProductName"

In this way prefs will be recreated.
WTF...

 

Maybe make a bug report for it

 

Thanks so much. Such a drag trying to find this.
