FortiClient v6.0.0.0067 Error when creating new VPN connection

[antrr1]

After upgrading the client for the v6 i cannot create a new VPN connection, the following error appears when saving the connection

I guess the error might be in the client certificate option, cause even the connection don't use it the dropboxlist looks weird. When i click on the arrow it dosen't show anything.

Thanks for the help!

I can reproduce this error with FortiClient v6.0.0.0067 on a Windows 10 (1803) machine with no user certificates available to select.

> Assertion failed! in document.h Line 1473, Expression IsString()

Works on a Win 7 machine with certificates available to select and the ComboBox displaying "Keines" (none).
