I'm trying to install Zabbix Agent on a Windows Server 2022 host and when starting the service it issues an error in the log when crashing:

Server and proxy are 4.0 LTS, up to date. I tried reinstalling the agent at the current version and older versions. I tried compatibility modes. There was no change in outcome.
