Hello @Stefanshine,
We have seen a few reports of a similar behavior, and so I do not believe you are the only case.
I am not able to see if the team has reproduced the specific error trace in-house at this time.
We’ll be in touch as soon as new information is presented. Thank you! 
Hi @Stefanshine,
There’s a potential fix for this problem undergoing testing in the latest Early Access release of Roon.
If you want to migrate your server and remotes over to the Early Access branch to download and test the fix, you can follow the instructions here:
If you find issues with the Early Access branch, please post directly in the #early-access category for our QA team to follow up.
Alternatively, you can wait until the fix filters into an upcoming Roon public update. We’ll share any anticipated timeline here.
Thank you again for your report and for your patience. We’ll watch for your reply in the meantime.
