Zulucrypt: Insufficient privilege

Everthing was working fine then on next power-on when I tried to open zulucrypt -using “Open _Volumne Hosted in a file” and login with password- I get this message.
“Insufficient privilege to open device in read write mode or device does not exist”. I have also tried to open another folder still this 2nd folder unable to access.

I am running Opensuse 15.6 and running Zulucrypt Version : 7.1.0
Thanks for helping.
