I have an off-and-on again problem with tag filtering working in Zotero 8 on my Win11 25H2 PC. Viewing My Library (whole collection), when I click a tag, filtering often freezes on that tag. I am unable to unclick the tag, remove the filter, or switch to another tag. What I have found is that if I move my mouse up to the My Library section and click on that or a collection name, that usually unfreezes tag filtering. I can then turn a tag filter off or switch to filtering on another tag - until it doesn't work again. Then a trip back to the My Library section rescues me again. I can't recall ever having this problem with Zotero 7. I will see if I can generate a Debug ID when I am having this problem.
