Failed to load project from file

Hi there,
i am unable to reload saved projects into soapUI. Beacuse of this i need to configure the project every time i restart soapUI. I tried saving different projects but no luck.For my collecgues its working all fine. I wont be able to share the project xml becuse of security concerns.
Thanks in advance.
Please find the error log from soapUI below
