Not showing thumbnail

[thoughtcastapp]

Installed on latest build of catalina, when I installed and relaunced finder, the webp images show up on quicklook, but the thumbnails still show the default image. Is there any way to show the thumbnail of the image itself?

Installed it on 10.15.6 and doesn't work, even after restarting Finder.

Can confirm both thumbnail and previewnot working on 10.15.6 here either

Both thumbnail and preview not working on 10.14.6 (Mojave).

Not showing thumbnails nor opening in Preview in 10.13.6 (High Sierra)

Don't think thumbnail or preview are working on 10.15.7
Is there a fix?

Works for me on 10.15.7. Installed like this:

# install
brew cask install WebPQuickLook
# bypass the "developer cannot be verified"
xattr -d com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator
# manually reset quicklook satellite
qlmanage -r
# restart finder
killall Finder

Then messed a bit with the thumbnail size in Finder, tried quicklook on a webp file, and all worked
