Are there any regions in the Russian Federation with active independence movements?

I'm curious if there are any active separatist movements in the Russian Federation. By "active", I mean politically organized, funded and regionally supported to the extent that they could relatively quickly seek independence from the Russian Federation.

A quick scan of Wikipedia article shows dozens of independence movements in Russia, but no indication is given about how serious they are or how much support they have in their respective regions. The sourcing on the page looks a little dubious as well.

In all of the scenarios I've read about concerning how the Ukraine war ends, none have proposed a scenario where the Russian Federation fragments under the double whammy of economic collapse and a military that is preoccupied elsewhere. Are there potentially breakaway regions that might be emboldened by recent events?
