Then it's your side having the problem. Most problems directly following a FileZilla update come from a firewall not liking the change in the executable and then blocking or interacting with it in strange ways... Normally redoing the firewall exceptions for FileZilla fixes that.
Note the term ''firewall'' is meant to be interpreted loosely, antivirus, antimalware software and routers have built-in firewalls, too.
