DNS Suffix issue after update to Windows 10 2004

Thank you for your reply. This issue occurs without any device management application.

In my environment, the administrator distributes 66 domains to DNS suffix search list as following registry value via script although it works correctly only top 50 entries.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\SearchList

In Windows 10 1909

If it has 66 domains in DNS suffix search list, it can resolve DNS server address.

In Windows 10 2004

I cannot access any network resources because it cannot resolve DNS server address like below.

I know it is the best way to reduce the entries to under 50 but  I would like to confirm this issue appears only my environment or not.
