Hi Does your file path contain any special characters or non-ASCII characters?

Actually yes, but how can I rename the user? Or would you advise something else?

If you use a custom location for your "Temporary files location" that doesn't contain any non-ASCII characters in the path, then Burp should use that location to save your BApp files and other data. You can find this option by searching in the new Settings panel on the latest versions of Burp. This issue is caused by Jython not being able to handle non-ASCII characters in the file path, rather than by Burp.
