blur background

Please check out the system requirement for using a virtual background on a Mac: https://support.zoom.us/hc/en-us/articles/360043484511-Zoom-Virtual-Background-system-requirements

I would recommend updating to the latest Zoom client, restart the client, and try using blurred background again. Thank you for using Zoom.
