Extension doesn't load, gives error
Burp Suite Community Edition v2025.3.4
V1.0.1

tried unloading everything except burp, didn't work
tried relaunching burp with extension, also didn't work

Removing Collaborator functionality for non burp professional users would be great :)

I encountered a similar issue, but after reinstalling it from the official Portswigger store, there were no error messages anymore.
