 I have a problem with Gutenberg since upgrading to the version above
 `5.7`, including `5.7.1`, which seems like a bug to me. If I refresh,
 sometimes it works, but usually not.

 All plugins have been deactivated, including `/mu-plugins/`, and a shipped
 theme activated. Same issue in Google Chrome and Chrome Canary. **Safari
 works, but it takes several seconds for the UI to be clickable.**

 Downgrading to `5.6` works, too, but this can't be the right solution.

 Here is [the error log](https://paste.ee/p/NRCuh) that was logged when
 Gutenberg didn't react.
