More info below. I come from v0.30.x so I found in the release notes I needed to change fullScreenLogs to fullScreen. Which I did but now I get an unable to activate context error (see logs below). I can't figure out what's wrong with my config (based on the changes/releasenotes I find in all v0.31.x)... Am I missing something?

@chrisv Sorry. Thank you for the great detail Chris! Indeed please take a peek at the Breaking Bad! section in https://github.com/derailed/k9s/releases/tag/v0.31.0 and/or https://youtu.be/X3444KfjguE
I've make a big mistake making k9s bomb if the configs are not up to par.
Will relax this a bit in the next drop...

Thanks. Just updated my previous comment with extra log info because I'm a bit stuck even after updating the config... I'll take a look at the video when I've got some more time.

Meanwhile I'll go back and stick with v0.30.8 which works fine on my config/system...

@chrisv Tx Chris! Looking like you don't have a current context specified in your kubeconfig?
Does v0.30.8 kick in contexts view upon launch?
If so please take v0.31.4 (coming soon...) for a spin.

@derailed Installed and tested with 0.31.7, and can confirm it's fixed.
Also: indeed there wasn't a current context (I create/delete clusters very frequently for dev/qa), but that wasn't a problem with 0.30.8, as it indeed did opened in contexts view upon launch.

Many thanks for all the great work and for the fast response & fix. Very much appreciated.
