Process doesn't have loaded .NET runtimes

I have a problem. Once in a while I use Attach To Remote Process. It used to work perfectly for months. Suddenly, not so long ago, everywhere I tried, I got the error in my Rider “Process XXXX doesn't have loaded .NET runtimes”. I do everything the same as always and have no idea what changed that it stopped working. I tried today on 5 completely different servers with different projects and all of them worked this way earlier, so I guess it's related to my Rider, not the remote environment. I don't remember changing anything locally, it's my work system that I don't do anything besides work. I don't remember exactly when I stopped working because at first I though it was something with the server but it was a few weeks ago. Yesterday Rider was updated to 2026.1.1 but it didn't help.

Hello! 
The case you've described looks similar to a known one: RIDER-138236 Debugger not attaching to remote process. It helps us a lot if you can share your logs. Could you please reproduce the issue and collect logs: 

  1. Go to Help | Diagnostic tools | Choose Trace Scenarios;
  2. Enable the trace scenario for Debugger;
  3. Reproduce the issue;
  4. Collect logs via Help | Collect logs and troubleshooting information. 
  5. Disable the trace scenarios enabled;
  6. collect also %LOCALAPPDATA%/JetBrains/RemoteDebugger/<RiderVersion>/Logs on the remote machine 

You can attach them to a mentioned issue or use JetBrains Uploads service and share the generated Upload ID. 

It is also worth trying disabling rider.debugger.dotnet.mixed.mode.enabled registry key in Tools | Internal actions | Registry 

Thank you in advance and have a great day!

I've downgraded to the latest 2025 version and it works again. Unfortunately I cannot send logs from connections with my clients so I'm just gonna wait until it's fixed.
