Toggle block inserter cause posts to close unexpectedly
-
We’re having issues with the “toggle block inserter” component. When user attempts to utilize the “toggle block inserter” in the upper-left-hand-corner of a post, it closes the post and says “The editor has encountered an unexpected error.” The full error code is posted below. Adding a block in-line works, but only if a user searches for the block, hitting “Browse All” in this menu fires the same error.

TypeError: Cannot add property width, object is not extensible

Hi there, I did a test on your site, and can reproduce the error. I checked the error logs, and disabled the Gutenberg plugin, and the issue resolved.
Did this just start happening, or has it been happening for a while?
There may be another plugin conflicting with Gutenberg. You can use the Site Health Troubleshooting feature and disable all plugins and then enable Gutenberg, Jetpack and the theme you are currently using, and test. Then re-enable the plugins one at a time and test to see if one of the other plugins is conflicting.
