Problems with Serialization

Hi everyone!
I’m having an issue in running serialization procedures: the example programs in bin/examples all throw the error message “Error writing Serialization of the crypto context …”.
I followed the build procedures on a Ubuntu 22.04 VM and all examples are working fine except for the ones involving serialization.
I might have missed additional procedures that are required to make serialization work, I simply followed the installation guide.

Thank you in advance!

If anyone else is having the same problem it’s sufficient to create the directory demoData in the examples folder, it’s printed in the code but I didn’t see it in the Docs.
Sorry!
