Welcome to the Hookmark Forum , @holamigo. Does the following tip from No Linkable Item in … – Hookmark help?
The macOS accessibility permissions database can get confused. In that case you might see strange behavior like not being able to disable or enable permissions for an app. In that case, you may reset Accessibility for Hookmark as follows:
tccutil reset Accessibility com.cogsciapps.hook- Reboot your Mac.
