Q: plugin com.apple.messages.ShareExtension invalidated
Trying to share a link in Safari via Messages. Click on the share button, select Messages in pop up list, nothing happens. I find this (which seemed most directly related) in the log:

Sharing using other methods seems to function properly. This did not start happening right after upgrading the Mac OS. I've been running this system for many days. Disabling extensions did not yield any change.

Please follow the instructions in this support article. Instead of typing the shell command directed in the article, I suggest that you copy and paste it from the web page into the Terminal window. Make sure you select the whole line. One way to do that is by triple-clicking anywhere in the line.
If you don't already have a current backup, back up all data before proceeding. You may have to log out or restart to see a change.
