Windows 10 April 2023 update causing tcpip.sys BSOD

[Guest EKSG01]

I am running a domain with Windows 10 and 11 on network. After the recent Windows Patch Tuesday for April 2023, I am starting to have Windows 10 PCs reporting BSOD with stop code DRIVER IRQL NOT LESS OR EQUAL, failure pointing to tcpip.sys.This happens to both desktops and laptops running on Windows 10 22H2, and running on LAN connection.A quick check on tcpip.sys shows that it was modified on the same date the April 2023 update was applied, but even when I overwrite the file with a older version from a non-updated PC, the BSOD still comes back.
