I am going to update to 1903 to see if this solves the bug.

Update: It does not.

Are you handling EXCEPTION_DOUBLE_FAULT in your exception handler?

[nicholaskunes]

I don't have time to check at the moment but will update tomorrow. As far as I know, this is the base (unedited) master branch of your repository ExceptionHookingDemo.sys, so your answer should be there. It Bugchecks immediately.

[can1357]

If you are testing ExceptionHookingDemo as is, __debugcheck should not be causing a EXCEPTION_DOUBLE_FAULT.

Would be nice if you could check where it fails or send a minidump.
