Gnome Shell crashing recently

Anybody else having issues with gnome-shell crashing after leaving computer idle for 20+ minutes and coming back to it? I know, issue sounds really weird, but this is exactly how I am experiencing issue.

I am using Acer Swift 3 with intel graphics and no proprietary drivers of any sort on it and this issue started happening in the last week or so. Same issue is also occurring on brothers laptop as well. As he has same laptop I'm not sure if that's something related to some particular component of this laptop or what.

This is model with Intel i5-7200U processor.

Anyhow, below are entries from journalctl from the time of crash:
