When I try to launch NeoLoad, I receive the following error: Unexpected error while loading project: org.xml.sax.SAXParseException; lineNumber: 20; An invalid XML character was found in the value of attribute "hostname" and element "lg-host".
Is it really when you launch NeoLoad or when you open a project?
It sounds to me that it's when you open a project that seems corrupted.
At the root project folder you should have some config.zip.<timestamp>.bak files. You can try to rename one of these file to "config.zip" and open again your project.
