Hi @eanticev, I just invited you to the Slack channel, so we can discuss your issue there. I am currently out of office and I don’t have the code to double check, but it seems that an FSM is ticking but its context object has been released by the garbage collector. I will look further into the issue as soon as I am back. As a stopgap measure, you can try replacing the offending Assert you should find at GCFSMState.h:112 with a
if(IsUnreachable()) return;
.
