Answer:
This message means that the connected project folder (for a block) is not found. This may happen, for example, if the folder has been renamed or moved after creating the block.
If you do not need this project folder for the block anymore, you can use the [Disconnect] button in the dialog box to remove it from the management. However, if you still need the project, click the [Skip] or [Skip All] button (if several folders are incorrect) to close the dialog box, and note the file paths.
You can use the "Connect Folder" command in the Block Manager menu "Category" to integrate the folder as a project in Block Manager. Click the [Browse] button to specify the folder and enter the project name.
In the Block Manager menu, you can also create a new project and connect it to the new path.
