Soap UI crashes after splash screen

I have installed SoapUI 5.5.0 using the .sh file on ubuntu 19. 

 

I executed the command sudo bash SoapUI-x64-5.5.0.sh

 

After installing the program appears with the question to enter my name and email address. When I click skip or after entering my details, the program stops.

 

I have tried restarting the PC, but this does not help. I also ran /opt/SmartBear/SoapUI-5.5.0/bin/soapui.sh > ~/Downloads/soapui.crash.log 2>&1 and included the captured log file.

Any help is appreciated.
