Strange start behaviour DP 5.1

meanwhile I get this notifacation v e r y often:

What is wrong?

Hi @Piano_Vink , that wait and warning dialog we built into Dorico mainly for the first time run after installation. Because if you have lots and lots of plug-ins, they first need to get scanned and that might take a while.
However, after the first scan a cache of already scanned plug-ins gets created so that during next startup not everything needs to get scanned again, but only newly added plug-ins.
That you get this dialog so frequently is not expected. Could you please create a diagnostics report and attach to a reply here? Thanks
