Videos won't register as played/watched/seen and won't show in the video history

Script version 5.6, also seen in 5.5 already

Describe the bug At the moment (at least going on for 3 days) I keep seeing the same videos I already watched in my YouTube feeds (frontpage, recommendations). There's no hint they've been watched and no time stamp has been saved. Most videos also don't show up in the video history. When disabling the script it seems to work properly and the videos I tested it with haven't shown up again in the feeds yet and have appeared in the history.

Expected behavior YouTube registers when a video has been watched, saves time stamp, displays "seen/watched" label on the video thumbnail, shows watched videos it in the YouTube history.

Desktop (please complete the following information):

• OS: Windows 11, Version 10.0.22621 Build 22621
• Browser: Chrome
• Version: 126.0.6478.62 (also previous version, since I received this update for Chrome just a few minutes ago)
