Blue screen: HTTP.sys error

Thanks. I could not find anything else apart from IIS error. Has the issue raised after Patch Tuesday updates aka after 8th?

Please check for updates on Ethernet and WiFi drivers.

Happens for us also on multiple computers. Seems to be related to some Windows update, but not sure which one. Some people reported it after installing 21H1, but seems to happen for some people also on 20H2.

The current workaround for us has been to run the sites on local IIS, until there's a fix available.

(I've updated my system to the latest BIOS (HP HP EliteBook 840 G7 Notebook PC) and updated all drivers, but that had no effect.)

So this started happening to me late last week.

VS 2019 BSOD whilst debugging. Crashed on me 4 times on Friday afternoon alone.

I ended up reinstalling Windows 10 yesterday afternoon. It made no difference.

So I tried VS 2017 this morning, and now it's doing it as well. I started a memory diagnostic just before I found this thread.

I have a feeling this is connected with the recent Windows updates.

I also have been getting the http2 protocol error in dev tools, along with other js files refusing to load. Reloading the page fixes it sometimes, but it definitely feels like the behaviour is getting worse.

I've given up trying to develop for now...

I am also getting random BSODs when using IIS Express, but there is also another problem that occurs when the BSOD doesn't occur.

When I create a new project in ASP.NET Core and run it from VS 2019 by pressing Ctrl-F5, there are two situations which occur randomly:

• Sometimes the app launches correctly, but some http requests fail randomly (approx. 1 of 10 requests).
  Edge shows HTTP2_PROTOCOL_ERROR in Dev Tools, but when I look in the server log, the request reports http 200.
  When I run Fiddler which plugs between the browser and the IIS Express, all requests succeed so I suppose this must be something between the browser and IIS Express.
• Sometimes I get BSOD right after IIS Express starts. It reports some problems in http.sys.

When I ask Visual Studio to run the project as a console app, the issue doesn’t occur – everything works correctly.

It happens on two different machines, one has .NET 6 Preview 4, the other one has only .NET 5.

I am not sure when it started, but it seems like it can be related to update to VS 16.10.

One of my customers was also reporting the same issue so I suspect it has nothing to do with hardware or drivers.

I am having the exact same issue, just started today, Visual Studio 2019 and IIS Express when debugging our web application.  Two other members of the team having the exact same issue under the same conditions.
