I guess you have an Atheros bluetooth adapter?
If so, there is a problem with the driver in 5.10.x kernels, see for instance https://forums.opensuse.org/showthread.php/548338-Bluetooth-cannot-find-adapters?p=2994265#post2994265
Maybe you can still find a 5.9 kernel in the archives, see here for instance http://download.opensuse.org/history/20201223/tumbleweed/repo/oss/x86_64/
