Problem:
The user would like to use the Gutenberg editor on the frontend.
He also wants to be able to upload files from the frontend.

Solution:
There is no way to load the block editor on the frontend with Toolset. The only way I know to load the block editor on the frontend is using this plugin, but I don't think it will be working with Toolset Forms. There is no official WordPress support to use the Gutenberg editor on the frontend.

Note that it is required that the user has the “upload_files“ capability(by default, authors and above). Check the table on this article
