iOS developement with Windows

Hi, first: I am on 4.26.0, not the preview version.
I am developing on Windwos 10, so I setup everything, also remote build with a macbook pro and everything works fine so far, except I can not Launch my app on the iPad 12 Pro.

If I use the Windows 10 App of iTunes I can build my app and also push it on the iPad with the iPhonePackager. But if I want launch I get this error: AutomationTool exiting with ExitCode=-532462766 (-532462766)

If i use the Win 64 Programm of iTunes for Windows I neither can build my app (ue4 links me to the unreal engine documentation) nor can i launch the app because I don’t have the iPad as a select option on launch. Just my windows machine occurs as an option.

I wonder if no one else has this problem.

I want to launch because its a bit faster than pushing the app from hand with the iPhonePackager and also I hope I get console output if for example my app crashes on launch.

MacBookPro has the latest stable Big Sur version,
iPad has the latest stable iOS version,
XCode is also on the latest stable version,
Also Windows 10 is on the latest version with all updates,
And iTunes (not the Windows 10 App) is also on 12.11.0.26 .
