Whenever I open the Image Labeler App and try to load images, I get the follwing error message:
Error using vision.internal.labeler.tool.Layout/hideTabXCloseButton
Java exception occurred:

Error using vision.internal.imageLabeler.tool.ImageLabelerTool/appendImage
Undefined function 'appendImage' for input arguments of type 'struct'.
How can I fix this?

This is an existing bug in 2020a. The file names must have at least two characters or two digits. As a workaround, if the file name is 1.jpg then rename it to 01.jpg.

Hi,
You can load unlabeled images data into Image Labeler app from a folder, images stored in datastore, or from a labeler session. Make sure that images must be readble by imread

'even if i use imds to load the dataset', does imds means imageDatastore? Are you able to read images with imread ?
