When using the Office schemas (https://learn.microsoft.com/de-de/office/client-developer/office-uri-schemes) in Chrome on a blank page to open a file, PowerPoint can't read/open the file as it fails to read the special character. Special characters of interest are the german Umlaute (ä,Ä,ö,Ö,ü,Ü,ß).
Example call would be: ms-powerpoint:ofv|u|file://C:/some_path/Test_Ü.pptx
The path included in the error message is then: C:*some_path*\Test_%C3%9C.pptx so there is probably some encoding issue.
