The type initializer for 'SecretsManager.CryptoUtils' threw an exception

[Pingu]

Hello,

I am trying to connect Keeper Secrets Manager in Rocket Remote Desktop 2026, but I encounter a cryptographic exception when initializing the store.

Steps to reproduce:

1. Go to Tools -> Settings -> Environment -> Keeper Secrets Manager.  
   
2. Switch to Personal Values tab.
   
3. Click on Initialize local config store and paste a One-Time Access Token generated from Keeper.
   
4. Click OK.
   

Error message:

• Initialization of local config storage failed.The type initializer for 'SecretsManager.CryptoUtils' threw an exception.
  

Troubleshooting already tried:

• Executed Rocket Remote Desktop as Administrator.
  
• Cleared %APPDATA%\Rocket Remote Desktop\ cache and removed profile.xml.
  
• Generated new One-Time Access Tokens from Keeper.
  

Update / Additional Context:

• This feature worked without any issues in Rocket Remote Desktop 2025. The problem started occurring immediately after upgrading to Rocket Remote Desktop 2026 a couple of weeks ago.
  

It seems like a regression or an issue with updated SecretsManager.CryptoUtils assemblies introduced in the 2026 build maybe.


Could you please advise on how to fix this issue or what dependencies might be missing on the OS level for CryptoUtils to initialize?

Thank you!
