Open Vue Devtools, click on "Settings (new)" tab.
Settings pane opens.
Vue Devtools freezes. I need to close Chrome devtools.
Reopening https://github.com/vuejs/vue-devtools/issues/1061 as it's unresolved but didn't use the template.

The problem seems to be only in Chrome. In firefox I could not reproduce this issue.
Error I pulled from the vue-devtools frame console.
TypeError: Cannot read property '$options' of undefined

This is a known bug (#979) when blocking third-party cookies. See the workaround that works for me over here.
Thanks @hay, it worked indeed. In Brave I found the settings in chrome://settings/content/cookies?search=cookie. Click add in whitelist: chrome-extension://nhdogjmejiglipccpnnnanhbledajbpd/ which will be translated to:

I think we should let the issue open for googlers.
I submitted a PR #1102 to fix this but so far haven't gotten any response, @Akryum any possibility to merge this?
