@verus what did you change in your my.ini? Trying to track this down and the ESET error and my Google searches for "big blocks" and MySQL don't seem to turn up anything helpful.
For anyone else looking for this I found this in the documentation:
Q: How do I configure MySQL to accept large packet size?
A: Locate your MySQL configuration file (my.ini for Windows and my.cnf for Linux, exact location of the .ini file
might differ from one operating system to another), open this file and find the section [mysqld]. Add a new line
max_allowed_packet=33M (value must be at least 33M or greater).
