zabbix-server crashing every 10-15 seconds (Zabbix 7.2 mariadb 11.5) fresh install

[ftb3]

I have 9 hosts back in my fresh install the following block happens at the crash, the kicker is, i'm not running any trappers of any kind in the zabbix_server.conf. I'm not sure what to do, i' have been trying to get this to work for a week now, splitting db to it's own server doesn't fix it, running all three 'appliances' on one server doesn't fix it.
mariadb 11.5 clean install status (with the only edit to my.cnf to be bind-address=0.0.0.0" just says "updating tables if needed" but the error log is full of (Got an error reading communication packets) again this happens even if i do it in an 'all in one' configuration, 2 servers (app/web + dp) or three servers (app + web + db).

It all ends the same, trappers I"m not running keeps zabbix from working, and crashes the zabbix-server service, meanwhile, apache, and zabbix-server and mariadb no longer get alone after 7.0.2 (The last time i had anything working) lol

I admit I am new to zabbix, *nix and databases (since august this year). So I'm just confused and want to learn, so I do I don't know an answer, be gentle lol

here's a grep for the word trapper from my conf file:
sudo grep -i "trapper" /etc/zabbix/zabbix_server.conf
# Listen port for trapper.
### Option: StartTrappers
# Number of pre-forked instances of trappers.
# Trappers accept incoming connections from Zabbix sender, active agents and active proxies.
# At least one trapper process must be running to display server availability and view queue
# StartTrappers=5
### Option: SNMPTrapperFile
# SNMPTrapperFile=/tmp/zabbix_traps.tmp
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
### Option: StartSNMPTrapper
# If 1, SNMP trapper process is started.
# StartSNMPTrapper=0
# List of comma delimited IP addresses that the trapper should listen on.
# Trapper will listen on all network interfaces if this parameter is missing.
### Option: TrapperTimeout
# TrapperTimeout=300
