fcbtest not working on bionic

When I try to run the snap in a bionic machine this error appear:

ubuntu@juju-79be25-0:~$ fcbtest.rallyinit
Traceback (most recent call last):

ImportError: /usr/lib/python3.10/lib-dynload/_decimal.cpython-310-x86_64-linux-gnu.so: failed to map segment from shared object

During handling of the above exception, another exception occurred:
