Issue: System.NullReferenceException thrown at gsudo start

[kintrupf]

When starting gsudo.exe i get this exception:

Error: System.NullReferenceException: Object reference not set to an instance of an object.

It takes a few seconds for this message to appear in the console window after the credentials were entered in the UAC prompt. Obviously, no elevated shell is started. I have a separate user with admin privileges. On another system where I use gsudo with the same user/admin user configuration all works fine.

gsudo version is 2.4.0. This is the output from gsudo --debug:

You have identified a bug in the CacheDuration config setting. You have set a cache duration greater than 24 days, which triggers this bug.

You can reset the cache duration to 30 minutes or you can set it to Infinite to avoid triggering the bug.

Please open a CMD or Powershell console as administrator (the old way, right click, run as administrator) then run:

• gsudo config CacheDuration --reset to revert it to 30 minutes OR
• gsudo config CacheDuration Infinite to let the cache live forever (it will close when the caller/allowed process is closed)

Then please do not close this ticket as this bug root cause is still not resolved.

Thank you for reporting!
