RDM crashes after update to 2025.2.13.1

Hello,

Thank you for contacting Devolutions Support.

As per the crash logs, you have provided us, this issue is caused by a Faulting module in Windows:

Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll

Per the information we have gathered on that matter, this issue is tied to Windows and not RDM itself.
For this reason, the only thing we can suggest is to run the following tools:

1-Run the .Net Framework Repair Tool: https://www.microsoft.com/en-ca/download/details.aspx?id=30135
2-Run SFC Scannow - https://support.microsoft.com/en-us/kb/929833

Hi,

I would need some information about your SSH sessions: are they using GSSAPI or SSPI authentication? are they using Smartcard authentication in either CAPI or PKCS11 mode? Are you using an SSH agent? If yes, is the agent Pagent or OpenSSH, and is it provided by RDM or externally?

This would help me target more precisely my investigations into this problem.

Regards

In my case:

• "Use SSH authentication agent" is checked
• setup is a bit complex, it uses a ssh-key stored on a YubiKey. It follows more ore less this guide to allow ssh-agent authentication via the gpg-agent.

@hoelle666 Thanks for the info. It does narrow my research.

Sorry for the inconvenience.

I found a bug and I'm pretty sure it is the cause for your problem. I have made a fix and it will be available in our next release: 2025.2.14.0

Regards

OK, just for the record: I'm also using agent authentication. But as an agent I'm running KeePass with a plugin.

@eiben Thanks for the info. Since the KeePass agent is a Putty compatible agent, it does point to the same bug.

Let us know if the next release does not fix the issue.

Regards

@Denis Vincent I can confirm that the problem is fixed with 2025.2.14.0.

Thank you.

@Denis Vincent: I can also confirm, that a first test didn't crash RDM anymore.

Thanks for the good news, I'm glad I could help.

Regards
