FortiClient VPN 6.2.2.685, macOS Catalina, parse_remote_info crash

macOS Catalina, FortiClient VPN 6.2.2.685 crashes on three different SSL VPNs but works on two other.

I have updated/clean installed new management workstation with macOS Catalina. I have defined five SSL VPNs so far. Two of them work perfectly without any issue. Three others are not working. The VPN client crashes after TLS communication starts. The Console shows something like:

The icon in the menubar is removed, and the UI is non responsible. This is 100% reproducible here. The first VPN still works perfectly.

Downgrading VPN client unfortunately is not possible (I'll solve this problem using previous system).

Anyone seen this?
