I tried your save and I was able to load it and view the stability tab without problems(this is the screen which you were talking about, right?):

I even tried to play a little and won a war in which I conquered the Mamluks, Hausa and most of Morocco which increased the overextension to over 170% and it was still usable. I had some slowdowns, but I don't know if they were from the game or because my computer was acting up(I have some powermangement problems which cause the CPU to switch to its lowest speed).
One thing which you could try would be to change the display mode to borderless fullscreen in the launcher like in the following screenshot:
This could at least prevent eu4 from locking up your whole computer and it might allow you to see an error message.
You could also check if there is a new folder in "Documents/Paradox Interactive/Europa Universalis IV/crashes". If there is, you could attach the exception.txt here which might offer some clues.
Or you can try to
verify the integrity of game files and if that doesn't help, you can try a
clean reinstall as described in
