Anyone playing with Mac Os Big Sur?

Anyone playing with Mac OS Big Sur? Does it outright break ManyCam or is it “safe” to upgrade as far as compatibi.lity?

Am running Manycam on BigSur and it still works fine but not with WebEx. Seems the ManyCam virtual camera just became buggy even on using WebEx Web app
So far it’s crashed only once when ManyCam hung but after that it’s running smoothly
