Plugin disables GraphiQL IDE and turned my .htaccess to default

I followed this tutorial: https://www.youtube.com/watch?v=sd02yF4_T_o

After I uploaded and activated the plugin the GraphiQL IDE got disabled - it was loading forever..., moreover, my .htaccess file was turned back to its default and I almost lost valuable configuration. Happy I had a copy of .htaccess.

As of March 21st, 2024 + Next.js 13 the plugin doesn't seem to be relevant. :(
