Images aren’t visible in the new lightbox when added

Hello. After upgrading a project to version 6, images aren’t visible in the new lightbox when added. However, everything appears fine in the site preview and new projects. After restarting the program, the images appear, but when adding new ones, the lightbox is empty again.
This issue occurred when upgrading to version 6. Is there a way to clear the asset manager image cache? Or is it somehow related to this message about reloading old elements? Clearing preferences didn’t help.
