Problem with filterable grid

Hi !

I used your plugin to make a filterable grid for my custom post type Institutions Montréal. It worked just fine, but now it doesn\'t work anymore. The guntenberg block show this error message : \"This block encountered an issue and cannot be previsualised\" and the options don\'t show in the right panel. I tried to uninstall and reinstall the plugin, it didn\'t work. The other block types from your plugin work tough. I don\'t understand why. I really need the filterable post grid.
