The issue is known in cast-web-api, just didn't know it was crashing the windows gui. Thanks for letting me know. Sadly if the issue is the one indicated in the logs, it won't be fixed in some time. I need to fork and fix a library I'm using. I cannot give you an eta on that, but it will be fixed.

@vervallsweg

Does this issue affect all platforms? Can I work around it by doing the manual node.js or running on Android? Or will I get the same issue?

Cheers

Well, if you install cast-web-api-cli manually, it'll restart from crashes on it's own. The desktop app isn't as robust, due to limitations in electron.

Android is a mess right now. The node version dory comes with is outdated. The developer put some instructions in the app description in the play store, but I haven't tested it.

Great - thanks. I've gone for the manual install as you suggested and it appears to be working fine. Cheers!
