sound failing in Dorico Elements 3.5 Trial

I recently got the trial of Dorico Elemnts 3.5, but currently it is unsusable because playback doesn’t function. I have tried all of the output options as well as messing with the buffer size, which occasionally results in the left hand of my piano part playing but not the right. Does anyone know where I might be going wrong?

All suggestions are greatly apprediated.

Have you read through these troubleshooting steps?

Also, please create a new project from piano template and then do from the main menu ‘Help > Create Diagnostics Report’ and attach the corresponding zip file here. Thanks
