The user is experiencing an error message when using the Fields and Text block and trying to edit it: "This block has encountered an error and cannot be previewed."
Solution:
The user was advised to update all Toolset plugins to the latest version. If the issue persisted, they were asked to switch to a default theme, deactivate all plugins except Toolset and its add-ons, and check if the issue could still be recreated. The user was informed that the development team was aware of the block-style panel issue, and the related problem with the Fields and Text block had already been fixed.
