Whenever I open gnome screenshot app, it freezes my system and and logs me out. I’m on latest beta with proposed changes enabled. I don’t know how to debug or record logs. If someone can guide me through the process, I’ll be happy to help in resolution of this issue.

By “screenshot app”, do you mean GNOME Screenshots? Because since a couple releases screenshoting is built-in into Shell (you can see if you’re using it via clicking on it via quick settings)
Both. From the dropdown in the shell and the app when you search for screenshot
Also if you press the Print Screen key on your keyboard?
IDK about a dropdown in the shell to take a screenshot, that may be an extension? If you search for screenshot is this the app you open:
yes to all. I’ve disabled the prnt scrn button since I kept leaping to it unconsciously only to get logged out (must have happened like 10 times even during meetings 
). but I think this is all the same app. The quick settings, the button and the manual search for app (their interfaces look the same but maybe diff under the hood).
Are you sure you’re running GNOME OS 50 Beta? There’s no screenshot option in quick settings there. Or which extensions did you install to maybe add that?
With no extensions installed taking a screenshot in the beta works fine for me.
edit: ignore this, I’ve been overlooking that button for years
It’s supposed to be there since GNOME 43, and should only be hidden on the login screen.
Doh! I didn’t know that’s what that button is for 
I’ve been overlooking it.
I’d try:
- Note the time then take a screenshot and after you’re logged out, note the time you’re on the login screen and then log back in
- Open the Console app and run the command
journalctl -eb -p err— this jumps you to the end of the current system log, showing you only errors (to first focus on) - Between the time you took the screenshot and the time you were back on the login screen, are there any errors in the log?
last lines looks like the problem

seems like this was fixed in update. So marking this as solution and closing this.
