The error says "Read-only file system". Is / (or /var) mounted read-
only? Did you had a file-system failure where the kernel remounted the
file system in read-only mode?

1) due to an encoding error, pyzor is throwing an exception.
2) /usr/lib/python3/dist-packages/apport_python_hook.py is the exception
handler invoked (belonging to the python3-apport package)
3) This exception handler tries to write to
/var/crash/_usr_bin_pyzor.122.crash, which fails
I checked the permissions:
# ls -l /var/crash
total 0
# ls -ld /var/crash
drwxrwxrwt 2 root root 4096 Dec 8 16:45 /var/crash
# ls -ld /var/
drwxr-xr-x 18 root root 4096 Jun 23 2020 /var/
# ls -ld /
drwxr-xr-x 24 root root 4096 Nov 30 06:19 /
/var/crash is sticky, so why can't it write?
# cat /proc/mounts |fgrep crash
