I keep getting an error 2503 how can I solve this?
You didn’t say what operating system you use but let’s assume Windows.

Add it is a Windows error, not a LibreOffice error, you could see if Microsoft can help, for example, Redirecting

There’s even a dedicated Documentation/HowTo/Work around Windows Error code 2503 and 2502 - The Document Foundation Wiki page, but see also these remarks.
