Active checks Fatal error. Internal CLR error. (0x80131506)

[EdgarGR]

Hello,

We have a bunch of servers being monitored by zabbix and it really works fine.One day, all of a sudden, an item stopped working on a host.
I tried reinstalling zabbix-agent and different versions of it and always the same problem.

The error:
Fatal error. Internal CLR error. (0x80131506)
Aborted (core dumped)

At the logs nothing appears:
sudo tail /var/log/zabbix/zabbix_agentd.log

70155:20221107:132136.438 agent #5 started [active checks #1]

The item itself:
-User parameter for Linux.
-It just returns 1 or 0.
-Working on all the other servers
-Before it was working.

Any idea on how can I solve it or what's this error about?
