After the July security patches from the 10th, not only did we have BizTalk issues we also hit the error the following error after doing a IIS Reset. “The service did not respond to the start or control request in a timely fashion. (2147943453, 8007041d).”
See this thread IISRESET results in W3SVC stuck in stopping status after July 2018 patches that has some details about it.
According to that thread, it looks like Microsoft already has Mitigation patches for this issue already (released on the 17th).
