Kaspersky Password Manager (v 25.0.0.225) is crashing

[Renan Goulart]

Heeey, Kaspersky Support Team!

I am writing because my Kaspersky Password Manager (version 25.0.0.225) is crashing unexpectedly on Windows.

 

Problem Summary:

Immediately after I enter my correct master password, the application shows it is "decrypting the vault" and then abruptly closes without displaying any on-screen error message.

Technical Error Details (from Windows Event Viewer):

• Faulting Module Name: ntdll.dll
• Exception Code: 0xc00000fd
• Error Message: STATUS_STACK_OVERFLOW

Troubleshooting I have already performed without success:

• Restarted both the application and my computer multiple times.
• Ran the sfc /scannow command to check Windows integrity (no violations found).
• Performed a full, clean reinstallation of the application using the latest installer from the official website.

The issue persists after all these steps. I believe this could be a bug in the application or a specific issue with my vault file that triggers the "Stack Overflow" error during the decryption process.

Thank you for your attention. I look forward to your instructions on how to resolve this issue.

P.S.: Personal information in the screenshots was removed for security reasons. The technical error data is intact.

Hello @Renan Goulart, 

Welcome!

1. Check Windows version & OS *build* - make sure they're the latest commercial version & patch & not from Insider, Beta OR Developer streams -> use WINVER in Windows Search OR systeminfo | findstr /B /C:"OS Name" /B /C:"OS Version" in Powershell?
2. *IF possible* create a KPM Backup. 
3. *Update* Kaspersky Password Manager to the *latest* version (currently: v25.0.0.501) from -> https://www.kaspersky.com/password-manager#installation.
4. Recheck the original issue? 

Please share the outcome with the Community, when it's available? 

Thank you🙏

Issue description:
After entering my correct master password, the application displays the message “Decrypting vault” and then abruptly closes without showing any error message.

Troubleshooting steps already taken:
