This problem happen just this morning, whenever I make a selection on android studio, the insert cursor activate.

What I've tried: To press insert, ctrl + insert, fn + insert. It still does the same.
Updated from 3.5.x to 3.6.1. problem still persist.
Using a keyboard tester I don't see any bugging keys.
The problem does not happen on any other software, Intellij IDEA is fine, notepad is fine, etc
I've seen in another thread that disabling the "use block caret" option should help but it didn't

At this point I'm completely lost in this issue.
