Tribler crashing - network fixing problem - PackError: Could not pack item 7

Dear All,
A nasty bug is affecting the global network.

We have a fix. Tribler v7.1.4 with this bug repair will be available today on Tribler.org.

Details: students have been experimenting with code and triggered a bug. Tribler crashes when you create orders on our token trading market with a 1+ day timeout. The full error looks like this:
