Problems after update Version: 2.6.0

After updating the Classified Listing – Classified ads & Business….DEMO plugin today (07.11.2023) our WordPress site started behaving strangely. The HOME page almost went empty – Logo, Menu, slider and fotter disappeared and the styling and margins rules one the remaining text content was gone . If the link points directly to a other page than HOME, everything seems to work until you go to the home page.
When i disabled the Classified Listing plugin all went back to normal. But now i cant see my listings. The plugin is now disabled so the rest of the website is working. Any idea how to fix it?

Note: We have before this update, been using the plugin for more than 1 year without any problems.
