Cannot see screen share- just frozen screen of others when they share

[jenlp88]

Ever since I got a new work computer I cannot see someone's screen when they share. Instead, there is a frozen screen of everyone else in their squares attending.  It makes me wonder if its the settings on computer or something but why- why would my company have some setting on Zoom where I cannot see when people share.  Makes zero sense so don't think that is it.  And this is driving me bonkers!!!  Also this is happening with multiple different meetings- not isolated to one.  Thanks much!
