Thanks for the dumps, we'll check on this.

Oh my goodness I'm an idiot. I caught this crash yesterday prior to release, put in a fix and tested it, but forgot to rebuild the installer with the fixed driver. Very simple fix, but I'll probably have to bump the version just to be clear.

The fix has been released in Npcap 0.86. The commit that fixed the issue is f919f3f which was already in the source zip for 0.85 but had not been compiled into the driver.

Yeah ! Thanks :)
