Roon has been very stable until recently, and now it crashes every time that I try to start the Core. I have re-installed Windows, and re-installed Roon and restored from a recent backup. However, the same problem persists.
Unfortunately I can’t paste the whole of the Error Event, because many of the lines start with a less-than symbol, which appears to hide the text when pasted into a message here.
Please could someone in #support contact me, it’s frustrating being without music!
I will check the firewall settings if I can, but when I opened the new installation of Roon for the first time, Windows asked for firewall permission for both Roon and RAAT

Thanks - I have just tried changing Roon.exe & RAAT to both ‘private’ and ‘public’, but Roon crashed on re-opening, so that firewall setting didn’t make any difference.
I’m sorry to hear that this issue has been interfering with your listening. The team will more thoroughly review diagnostic logs from the Core device to try to pin down the issue, but a first glance through shows several network connectivity issues around the time of a crash.
To rule out a firewall: You can read detailed instructions for adding RAAT Server and Roon as exceptions to your Windows firewall in this article. I also recommend checking firewall settings on any Remotes you might have in use here.
Another immediate troubleshooting step is to set aside the Roon database (more thorough than an uninstall/reinstall):
thank you for your reply. I have done the following:
checked firewall settings (both Roon & RAATserver were set as exceptions)
changed Roon database folder name to Roon_Old
downloaded & reinstalled the Roon app
The Roon app started OK, but as I was entering my login details, it crashed, with the same error as before in the Windows event logs. Here’s a copy of the error event properties:
Can you give me any further assistance please? I don’t know what UCRTBASE_CLR0400.DLL is or how Roon should interact with it. Is this a Roon problem or a Windows problem?
The errors appear to be related to your .NET framework; it’s possible a file is corrupted.
Can you try to reinstall .NET Runtime and see if that helps? You can uninstall from Control Panel and then reinstall from the Microsoft website: Download .NET 6.0 (Linux, macOS, and Windows).
Please let me know if that helps.
Do you encounter this error when minimizing or maximizing the window at all? You mentioned logging in triggered the crash - do you remember the last action you performed prior to the crash?
Thank you again for working with us to chase this down.
Roon has been stable for years, and whilst recent problems (in past couple of weeks) of audio stopping appear to have been resolved by the latest software update, Roon Core now repeatedly crashes. It now crashes within a few moments of opening the software.
Event Viewer error log shows the following on each occasion:
I installed .NET Runtime (it didn’t appear to be installed, perhaps because I’d recently reinstalled Windows 10 to see if that would solve the Roon problem) and Roon appeared to be stable. Windows then did an update, and Roon became unstable again. I repaired .NET Runtime and Roon has been stable for several days until this morning when it crashed again with the same error as previously described in this thread showing in Event Viewer.
Is there any diagnostic check that you can do to establish if I have a hardware problem or if it is Roon software please? My Roon system has been ultra stable for years (since I first started using it in, I think, 2016) but now I’m cautious that every time I use it, it will crash.
My Roon Core ran OK for 5 days but crashed again (same error related to ucrtbase_clr0400.dll). I had been using it intermittently but I was not playing any music or interacting with Roon when it crashed.
Can you help me shed any light on what might be the problem please?
Thanks for the suggestions. I ran Passmark’s ‘Memtest’ as suggested, which passed 100%. I will send you the results by e-mail (or let me know if there is some other way to send the file).
I also ran System File Checker, and that completed OK without reporting any issues.
Do you have any other ideas as to what might be causing the error (Roon, or my PC?)
