your screenshot is kinda small to make out the file extensions... do you see the ComicBase Cover Gallery.scr file? If not, run the CB2022 program installer and do a 'repair' install. See if the file appears in that folder afterwards because that's the screen saver program.
If the problem doesn't fix with a repair install, email our support team directly at support@comicbase.com.
Do you recall how you initially installed CB2022? Did you uninstall CB2021 first? You're running on Windows 10?
