Hi @nwvitals.
I just updated to Gutenberg 11.5.0 using Twenty Twenty One theme. When I switch to Widgets screen there are no errors.
However, it’s perfectly possible you have a particular set up which is allowing an error to manifest.
I’d like to see if we can get to the bottom of this.
Please could you:
* Post error messages you are seeing.
* Open developers tools and post any errors shown in the Console.
Then also using a staging site (not your production site)
* Deactivate all other Plugins (except Gutenberg). Does the error still happen?
* Reactive Plugins one by one to see if you can identify if one causes the error to occur.
If we can identify the issue we should be able to determine whether a fix is needed.
Much appreciated.
