I updated to MacOS Catalina and now I cannot share my app screens. I can share my desktop, but that is all others can see.

My system had an entry (unchecked) for Microsoft teams. I think it asked me as I was launching but I blew by it. Not sure how you'd add it if it's not there. You just have to turn it on, and Teams screen sharing will work.
JustAGuyVA, as per several earlier comments in this post, start closing other apps until it works. It's ussually related to another app being opened. There have been several identified so far in this thread that cause this issue.
Here is a blog post (also posted earlier in this thread) showing the issue as well as a running list of the apps that I've uncovered that cause the issue - https://benstegink.com/microsoft-teams-and-macos-catalina-10-15-broken-screen-sharing/
It is definitely not working to close other apps. And for sure it is not a consistent behavior.
One time in all my testing I managed to get the screen sharing to work. That was after quitting all other apps AND a restart. However with subsequent tests the sharing stopped working again and this time even after a restart it did not work.
One time I managed to get it to work simply by going from full screen to window of the Teams app.
This is a Teams bug and not directly related to other apps.
Unable to share screens & application when "Photos" is running.
After quitting "Photos" sharing works again...
This doesnt work for me. Even I check the settings, it keeps asking me same thing?
I am facing same issue for Skype for Business as well. :(
