Same problem here. After the GSX menu popped up advising of an update that did not require a restart of the sim, I selected it. after that I needed up getting the same error "The addon <unknown> is causing the Couatl Scripting Engine to restart. Please download and install the latest Stand-Alone Addon Manager from.."
So I did that. Rebooted. Seemed to be working on the outbound departure just fine, until I landed 1:40 later and started the deboarding process. Process seemed to start ok, was marshalled into the bay, and I asked for deboarding then the same message came up again!
I ran the log and it gave this info:
couatl v3.1 (build 3487)

Never had this before this update. Umberto and team, please can you fix this annoying bug introduced into the latest update. I'm running P3D v3.2.
Thanks!
