Try Google Meet. I have a similar spec Air, and that's where it falls down :'-(

Google Meet is trash. Camfrog from over a decade ago trashes it, Zoom, and any other multi-camera meeting room software. I was watching over 150 video streams at once on a Pentium 4 using Camfrog, and now you can't even have more than 5-10 before a computer starts choking.

What garbage.
