Description of Issue

Streaming from Tidal to Linn DSM suddenly stops and the Roon application disappears. Log shows InvalidOperationException in mscorlib.dll.

Restarting the application solves the problem. This has happened a couple of times. Also last year using Qobuz (different computer, same DSM)

Hi @Henrik_Edstrom ,

Thanks for the report here.

We’ve gone ahead and enabled a deeper diagnostics mode for your account, can you please reboot your Roon Core when you have a chance, and then please let me know the time + date when you next see this crash occur on your end?

Also, can you please post the exception message you get, just to check if it is indeed the same as before? Thanks!

Note that it happened on Roon 1193. I just got 1202, will report if it still happens. Thanks.

Hi @Henrik_Edstrom ,

I wanted to follow up on your case - I activated diagnostics for your Core and I’m not seeing any more crashes with those traces. Can you confirm if the system has been stable?

Hi! It happened again. Build 1234 to Linn DSM.
Roon client and server on same computer. I think it always happens when also doing something else on the computer. However that’s usually when I use Roon so it might not be relevant.

Hi @Henrik_Edstrom ,

I recently spoke to the team about this and have put in an investigation ticket regarding this. If you are still seeing this at the present time, can you please let us know the exact local time + date of the next crash? I would like to attach a new log set from your Core to the investigation ticket, thanks!

Hi @Henrik_Edstrom ,

Our latest Roon release contained a bug fix in this area. Have you still experienced further crashes recently?
