FortiClient 7.4.6 crashing

Hello all,

I tried to update my devices managed by EMS to FortiClient 7.4.6, but all users on this version are not connected to EMS anymore. When I connect to the devices, it seems the FortiClient is not running.

When I start it manually directly from the install folder, the FortiClient is starting and tries to sync, but as soon as the countdown reaches 0 and the client tries to sync, the FortiClient crashes and stops running.

Anyone known what happened and if there is any workaround who not involved reinstall of the FortiClient in older version ?
