Thank you for the quick reply.

I'm not using any extensions, precisely to remove that factor when
testing.

Sure thing, you can find it attached.

The error messages in the gnome-shell journal are not terribly useful,
whether I open or not windows. It will still spit something about the
clutter stage. Sorry for not clarying this earlier. I will try to get
cleaner logs, meanwhile, the last bit is interesting.
-----------------------------------
After a bit more of testing, I can now reliably fix/reproduce this
issue.
1. I have a laptop and an external monitor. Sometimes I use this as a
two display configuration (laptop being the main display). When testing
this, my laptop lid was closed.
2. It seems that mutter assumed for some reason that my laptop screen
was still active. That's where the mouse was "hiding".
3. Upon opening a window, gnome-shell tried to open it in the display
where the mouse was. *Here* is the crash.
4. If upon logging in I move my mouse up (a lot) to "move it" to my
external monitor (from the ghost laptop display), then windows can be
opened safely and no crash happens.
So it seems that the display settings are behaving weirdly across
sessions.
To reproduce reliably (at least for me):
1. Use a two-monitor configuration (two active displays)
2. Log out while the mouse is in the laptop screen (primary display)
3. While in GDM, close the lid (so only the external monitor is on)
3. Log in, mouse is "lost"
4. Open a window quickly using the keyboard -> crash
Hope it helps,
Santiago
