I tried uninstalling GPU drivers and reinstalling the latest GPU drivers based on similar symptoms from other users on this forum, but that did not help.

Appreciate any suggestions to fix this issue.

Hi @nikhil_suvarna

Starting out, can you try the following:

• Reboot the Windows machine
• Download .NET Framework and reinstall it
• Follow the instructions below to remove GMS files

GMS Instructions

1. Locate your Roon database folder. Instructions for Windows can be found here
2. Inside this folder navigate to Registry → Client
3. Remove and files that start with GMS
4. Try to launch Roon once again

Next Steps

If none of the above helps, please use the directions found here and send us over a set of logs using a shared Dropbox link.

We’ll also want to take a look at Event Viewer logs, please send those as well:

1. Press Win + R and type eventvwr.msc
2. Press OK – this should open Event Viewer window
3. From the left sidebar go to Windows Logs > Application
4. Right click on the Application subsection and pick Filter Current Log... from the context menu
   
   
5. On the Filter tab for the Logged section pick a parameter Last 30 days and press OK
   
   
6. Right click on the Application subsection again and pick Save filtered log file as.. from the context menu
7. Enter the log file name, for e.g. Roon_USERNAME , and press Save

Hi @dylan ,

Thank you so much for your response and looking into my issue. I have the updated version of the .Net framework but I got the following error :
.NET Framework 4.8 or a later update is already installed on this computer.

I then tried removing the GMS files from the Roon folder (I have both Roon and Roon Server folders; Roon Server Client Registry did not have any GMS files)

Here is the link to the dropbox location with all the artefacts as requested.

Please let me know if there is anything else you need from me.

Thank you!

Hi @nikhil_suvarna

I just wanted to let you know that the logs were received and are with our QA team for further feedback. We’ll be in touch ASAP once they’ve been able to analyze the log files you’ve shared.

Hi @nikhil_suvarna

Can you try clearing the cache on this device?

• Find and open your Roon database
• Navigate to Roon/Cache
• Move the contents of the /Cache folder elsewhere, like your desktop
• Try restarting Roon and let us know if there is any change

I think I’ve had exactly the same problem as Nikhil - Roon wouldn’t start. I fixed it by updating my software and restoring the database from a backup. More specifically …

Same Messages
I got the exactly same error messages in the log as Nikhil, i.e.

Exception Source: Roon.Broker.Core
Exception Type: System.NullReferenceException
Exception Target Site: State…ctor
Exception Message: Object reference not set to an instance of an object.
Exception Data: none

What I’m running
I’m running a Roon Server and a Roon Appliance PC app on the same machine as well several other Roon appliances (e.g. on phones, other PCs, etc.). The Roon Server is running on a self-built Windows 10 Pro with an Intel i7 4770K with 32GB. It’s has an Ethernet connection.

What I tried and what worked
First I tried upgrading from v 756 to the latest version, v 764). After this the Roon PC App would now open but it could not find the server. The Roon Server was still failing with the same error as above.

I then restored the Roon database from a Roon Backup from 12 days ago and Roon is now working. I’m wondering if there had been a database corruption. Finally I did another manual backup of the Roon Database as insurance.
