Error importing existing project

I have been using the OpenSource 5.0.0 version of SoapUI without issues. Suddenly as of today (4th March 2109) the File > import Project is no longer working.

All the exising projects have been unloaded.

I upgraded to openSource version 5.5.0 which has the same issue.

The error show in SoaUI load and error log is as follows:

 

• Mon Mar 04 11:23:06 GMT 2019:ERROR:An error occurred [java.lang.NullPointerException], see error log for details

• Mon Mar 04 11:23:06 GMT 2019:ERROR:java.lang.NullPointerException
