After ZBX-20164 was fixed another issue can be observed using the same test scenario (though it takes 3+ hours now)
Steps to reproduce:
- Create a host that represents a working Windows machine (tested at Windows10 20H2)
- Add template "Template OS Windows by Zabbix agent" to this host
- Unlink the template
- Navigate to the list of items of this host and set update interval to 1 second for all items via mass update
- Start monitoring this host using a windows version of Zabbix agent2
- 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) Press Ctrl+C to exit.

Expected: no agent crashes should be observed
