Screensharing Kicks Me Out

Hi, this has happened to me several times now - when I go to screen share (whether it is a meeting I'm hosting or joining) it will automatically kick me out of the call. At first, I thought I was accidentally pushing 'Leave' instead of 'Screenshare' but now I'm certain that is not the case. 

I'm a Project Manager and I host a lot of meeting with clients - so, I'm looking to see if anyone has run into this or has a solution I can try. 

Thanks!
