Dependency Problem with c#.WebApi Solution in Folder with special Character

i have a very strange problem getting a RestFull-WebService with Asp.NET working with VS2019.. I'm setting up a default WebService Project and started it without any other changes..

My Solution is places in the directory C:\TEMP\WebSolution1... So the solution comes up sucessfully and the browser starts the webservice-welcome-page..

As soon i try to create the same project the the same settings in a different folder with a special character (C:#TEMP\WebSolution1) i'll get an exception:

System.IO.FileLoadException: 'Die Datei oder Assembly "Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" oder eine Abhängigkeit davon wurde nicht gefunden. Die gefundene Manifestdefinition der Assembly stimmt nicht mit dem Assemblyverweis überein. (Ausnahme von HRESULT: 0x80131040)'

at

HelpPageConfig.Register(GlobalConfiguration.Configuration);

Sorry for the german exception :-/

I'm not referencing the V6.0.0 of newtonsoft - instead the default project should references the V11.0.0 of Newtonsoft. So it looks like the searchpath stumbles across my "#" sign in the folder and picks a wrong assembly instead (maybe it's not the newtonsoft but on other assembly references newtonsoft v6....)

is that a fixable problem?? because all of my projects are stored inside a folder with a "#"-sign and it would be fine to leave them all at these place...

Maybe someone got a hint for me, how to solve it.

Thanks in advance
