Hello @lisa.oneill,
Welcome to the community!
When you remove and reinstall the LastPass extension by default it has you logged out and when you are not logging is normally in a black/grayish color. You will need to click the LastPass extension icon and should ask you to login. Please verify this installation steps: https://support.lastpass.com/s/document-item?language=en_US&bundleId=lastpass&topicId=LastPass/install-lastpass-extension.html&_LANG=enus and the enablement process here: https://support.lastpass.com/s/document-item?bundleId=lastpass&topicId=LastPass/enable-extension.html&_LANG=enus
If you need anything else, let me know.
Kind Regards,
Alejandra

I have the same problem. I reinstalled the extension on Edge, if I click the icon, it allows me to log in, but the icon remains grey and I cannot use autofill
