    Description

      After ZBX-20164 was fixed another issue can be observed using the same test scenario (though it takes 3+ hours now)

      Steps to reproduce:

      1. Create a host that represents a working Windows machine (tested at Windows10 20H2)
      2. Add template "Template OS Windows by Zabbix agent" to this host
      3. Unlink the template
      4. Navigate to the list of items of this host and set update interval to 1 second for all items via mass update
      5. Start monitoring this host using a windows version of Zabbix agent2
      6. wait for some time (can take approximately 3 hours) 

      Result: Agent crashes with the following output (but nothing is written to log):

      D:\Zabbix\agent\go_agent>zabbix_agent2.exe -f -c zabbix_agent2.conf
      Starting Zabbix Agent 2 [Windows host]. (5.0.18rc1)
