I believe this started ever since the latest major chrome web browser update, from 68 to 69. (currently on version 69.0.3497.100 )
Basically, when I'm using the chrome dev tools and debugging some javascript, the browser crashes when I begin typing a variable name into the console. I'll get a character or two in and then bam, the whole thing crashes.
I'll close the browser, reopen it and still crashes immediately when typing in the console. Sometimes there are a few hours in between episodes, but this has been a persistent issue for too long and is severely impacting my ability as a developer.
As pointed out on this Reddit post: Google Chrome 69 Issues, that particular version was riddled with bugs. One website, quoting here from the same reddit thread, titled their article as "Atrocious performance - Google Chrome 69".
While this is not a solution, the easiest thing you can do is update to the latest version. (70.0.3538.77, at the time of writing.)
