ffi_prep_closure(): bad user_data (it seems that the version of the libffi library seen at runtime is different from the 'ffi.h' seen at compile-time)

I am running few python scripts on my raspberry pi4 running Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-1034-raspi aarch64)..But today all scripts stopped working and I'm getting this exception in all of them..

I'm actually interested in the root cause of this but you can probably fix your issue by pinning the version of cffi to <=1.15.0.

A new version of cffi was published on 30 June which is, I presume, why you started seeing errors around that time.

I'm seeing the same error messages on Ubuntu 20.04 but not on Arch Linux.
