Hi, you can look to the wiki, this is a common error when updating, this is the right part of the wiki :

Config is invalid
Problem
You're getting a message, telling you that your config is invalid alongside with some weird technical-looking things. This can either happen if you upgrade to many versions at a time (I'm trying to merge configs from the previous release, if possible, so if you're upgrading from 1.4.0 to 1.4.1 you should be fine, but if you're going directly to 1.4.2 you might run into this error)

Fix
If you're unsure about what the errors mean you can always just delete that file rm ~/.config/octodash/config.json and reboot your Pi. This will open the initial setup screen again and will create a new, valid config for you. All your configuration data for OctoDash will be lost, OctoPrints data isn't touched.

If you understand what needs to be changed in your config please go ahead and edit it with your favorite text editor. You can find the config at ~/.config/octodash/config.json.

If you want more information about the config / settings have a look here.

so through SSH : you can sudo rm ~/.config/octodash/config.json then sudo reboot
it will reset the octodash config but it is really fast to configure so have fun :)

did you install an intermediate nightly build? That's why the automatic config fix probably didn't kick in. Either add previewProgressCircle: false to your config (under octodash) or remove the config and start from scratch (it's way easier to setup with v2.1.0!).

yes I tried a nightly build a few days before.
I removed the config.json and installed octodash manual, now everything works like expected. thanks for your support
