DataDavid I am also having this issue. My MacBook Pro updated to the latest version of Catalina yesterday 10.15.5.

Now no one can see or hear me in a Teams call and I cannot see or hear them either although I can see myself.

  AdrienneElle Anyone else using ESET Cyber Security? Might be that ESET causes the problem: https://forum.eset.com/topic/23439-microsoft-teams-issues/ They advice to customize the firewall to provide access to Teams Helper. No experience myself so far if it helps.

    DataDavid I was just researching this issue because I am unable to do video calls lately too and I came across your reply. I do happen to have ESET installed (an imposition from work). What are the modifications to the firewall required?
