Newbie. Ubuntu 21.10 Gnome. Nautilus file manager not working right.

[Advait]

Also, try creating a new user and see if the problem persists.

Update: I created a new Standard user and switched. Nautilus was operating normally. The multiple dots were appearing and the mouse hover worked normally (the open window thumbnails appeared). However, it looked different cuz I'm using Dash to Dock and the new user isn't. I expected that, of course.

So, how to fix?
-----------------
Hmmm.. Creating a new user... Never done that before. Let me start google searching how and I'll report back.

Any security risks in creating a new user?
