after uninstalling the updates KB4338815 and KB4338830 for the different Windows Versions, the 80% of the servers, the iisreset start working as it should, but still a large pool of servers are affected even uninstalling/rollback the update.
We have already opened a case with Microsoft so we can find a solution, i'll keep you posted.

Microsoft has already updated the update page with the known error:

Microsoft is working on a resolution and estimates a solution will be available mid-July.
