I skipped some steps. In Google PWD Mgr, go to Pwds and Autofill, then find LastPass occurrences and delete. You then have to make sure that
Google is not automatically saving your LastPass passwords or the issue will reoccur. I hope this work for you.
It's related to Chrome Password Manager. Go to Chrome, click the three dots in upper left, then New Incognito Window, then login to LP via browser.
I 'think' that will resolve the issue.
I have the same problem with no answer to this problem. So frustrating.
