Dorico "not responding" - new project creation

As the title suggests, after selecting the ‘Romantic Orchestra’ template Dorico begins loading the instrument sounds then hangs and becomes non responsive. This is on Win10 and repeatable after a restart. Sometimes I get the “serious error” notifiction about the VST Audio Engine having bombed. Could I please get some help with troubleshooting this?

Could you please repeat the unresponsive case, then restart and immediately execute from the main menu Help > Create Diagnostic Report.
That will create a zip file on your desktop containing log data. Please send it to u dot stoermer at steinberg dot de.
