FATAL:viz_main_impl.cc(246) error on startup 79.x debug 64

[user6294]

Hi

Thanks for your help on debugging the cookies issue.

I got it working, and it was running up nicely until an access violation error when returning from the cookies visit method. Which I was going to debug.

But all of a sudden now, I getting these two errors even before the network stack starts (I haven't changed the application code at all)

Q. what kind of conditions can cause this, I copied all DLLs from out\Debug_GN_x64 directory

Many Thanks

I'm not sure quite where to start looking.
