So just to clarify…..
It doesn’t happen when Image Extract is doing stuff? And it doesn’t happen when clicking a button in Image Extract? It only happens when clicking the the layer panel in Photoshop itself? Is that correct? If so then it seems that it is a Photoshop issue, not an issue with the Plugin.
Are you running Photoshop 23.3.2?
It may be a corrupted Photoshop preferences file. Please try resetting the Photoshop preferences. Then restart Photoshop. Let mw know if it continues to happen.
