Are you saying that you are getting the following message still...

Shared object "libffi.so.7" not found, required by "_gi.cpython-38.so"

... with the ldd -a output you attached (attachment 234479)?

Given that _gi.cpython38.so does not show any reference to libffi.so.7 in your
ldd output, then those two data points (the error message and the ldd output)
seem to be in conflict with each other.  There are ways to force references to
libffi.so.8 point to libffi.so.7 instead (e.g., libmap.conf, path to alternate
libs being used - like in /usr/local/lib/compat, etc.).  But I am assuming you
don't have anything unusual like that.

By the way, just for testing, I have a backup package of python38 that was
built against libffi.so.7 (the only shared object that references libffi is
/usr/local/lib/python3.8/lib-dynload/_ctypes.cpython-38.so).  I used that with
the other dependencies (_gi.cpython-38.so, etc.) updated to the latest (all
referencing libffi.so.8), and meld worked fine, even with no libffi.so.7
available.  So, as far as I can see, for your originally reported issue, it
should not matter if you missed an update to python38 (some comments in this
thread were suggesting that as a possible issue).

If you are still seeing issues, you could run 'ktrace -id /usr/local/bin/meld',
and analyze the kdump output and/or attach the result here. The ktrace file
would give an indication what might still be triggering the attempt to link
with libffi.so.7
