Hi kirkegrd9000,
I am but a moderator, but I DO believe in support devs, I do, I do …
Let’s flag down @mike and @vova to investigate. It will help if you can provide system details as per this post. How large is your library in terms of # tracks ?
There have been some recent reports of crashes with Windows 10 64 bit version. If that’s what you are using I’d suggest trying the 32 bit version of Roon for evaluation purposes as it appears not to have the same issues. You can then install the 64 bit version once any issues are resolved.
