Chrome Version: 63.0.3227.1 SyzyASAN 
OS: Win10

Looks like https://chromium-review.googlesource.com/c/chromium/src/+/649528. I don't have a crash ID, as I can't get to chrome://crashes ATM.

This has properly killed my official build SyzyASAN browser when DCHECKs enabled.

bool IsWindows10TabletMode(HWND hwnd) {
  if (GetVersion() < VERSION_WIN10)
    return false;

  if (!ResolveCoreWinRTDelayload() ||  << IN HERE
      !ScopedHString::ResolveCoreWinRTStringDelayload()) {
    return false;
  }
