Files from mail not working

From Mail is not working…

I installed From Mail:
I did exactly like here: https://github.com/nextcloud/files_frommail/blob/master/README.md

Why Nextcloud use …/20180731/… when there is the last one 20190902 ???
and there mailparse.so exist.!!!

PHP Startup: Unable to load dynamic library ‘mailparse.so’ (tried: /usr/lib/php/20180731/mailparse.so (/usr/lib/php/20180731/mailparse.so: undefined symbol: mbfl_convert_filter_flush), /usr/lib/php/20180731/mailparse.so.so (/usr/lib/php/20180731/mailparse.so.so: cannot open shared object file: No such file or directory)) at Unknown#0
