Looking at the log there might be a problem with auto generating Tx files and it could be because of the '~' character in the file name, like file_e32487de918d5b17~.tx Can you change the file name and render again?
Alternatively you can turn off auto tx generation in the render settings to see if that's the source of the problem. If so, you can generate tx files manually via the Tx Manager and use them in the scene instead.
I also see some compatibility issues in the log, like
[c4dtoa] 00:00:00 1246MB WARNING | alembic_proc.dylib was compiled against non-compatible Arnold 7.1.3.1
which suggests, that something's wrong with the install. Some files are left from previous plugin version maybe. You can try to re-install the plugin and make sure everything is up-to-date. Also make sure you use the same plugin version on all client machines.
