HALion Sonic SE 3 Error

Help please with this problem.
I’m using Cubase 9.5 Pro. When DAW remains some time open, this error appears and DAW stops working. Each time I have to do a restart of the station, after which everything works and Halion too. In the dialog box, the Close and Retry buttons are not active at this time.

I think the tech’ guys may need more info’
Is it a software E licenser or a USB Dongle type ?
I think you need to list what your pc is and which version of Cubase 9.5 Pro you have.
As it is i’d think the Licenser is at fault but you could try a fresh install.
