I have encountered such error when my xml was not encoded as UTF-8 without BOM. Please check this.

Are you absolutely sure it is UTF8 without BOM? Since BOM is the very first thing in the file. So it can absolutely cause this error.

First off, look at the XML file itself - make sure it exists, and then look at the content. The error message is very specific - it says that the first character in the file if wrong, so at a guess, it isn't a '<' character - it's probably the wrong file. The other possibility is that it's in the wrong place: this could be a permissions issue. It is a poor idea to store any data files in the exe folder unless they are always going to be opened in read only mode - very often, any write access opening will fail security policies in relesae versions, and you will get an error - so it could be how you are opening the file. If you need it to a be read-write file, then move it to a more useful place: Where should I store my data?[^] should help
