Have you contacted LastPass support?

My issue is with logging into LastPass in Federated mode. After Okta login/authentication, firefox has blank screen. this is both with Website and using Extension. Firefox 102 worked fine. Version 103.2 is where the issue appeared. I can revert back to 102 and LastPass works. Unfortunately, I cannot stop the automatic upgrade.

I am using Edge browser until this is fixed, or I become comfortable with Edge.
