On File Move the curly brace layout changes - why?

Question

I have Visual Studio 2022 and Resharper (latest versions). My Code style for curly braces is:

if(true) {
    //....
}

!!! While typing end editing code everything works great !!!

But as soon as I move a code file from one folder to another within the project the curly braces change to:

if(true) 
{
    //....
}

• I have tried the Option under Tools -> Options / Text Editors -> C# -> Code Style -> Formating -> New lines
• I also have set the corresponding Resharper Options to "K&R Style"
• I tried to disabled all analysers
• I tried to suspend Resharper

Is Visual Studio doing this (and if yes where could be the setting) or is it possible that any Git Tool is changing this? For Git I have "GitHub Desktop" and "TortoiseGit" (But I did not find any Options there)
