A few days ago I started getting this small window (Script Alert IOError: I/O error) after starting Photoshop. After clicking the „ok“ button in it, you can continue your usual work with Photoshop, but the Configurator Reloaded panel is inactive, empty, and only its title is displayed. Photoshop latest version 23.5.1. But this warning does not always pop up – as a rule, after booting the computer, the first launch of Photoshop is successful, the panel is loaded. But if to close Photoshop and open it again – then warning windows will pop up, and the panel is already inactive. In photoshop 21.2.12 everything is ok, the panel works.
