Bluetooth stopped working after the update to kernel 5.12 (Intel Wireless 7260)

Hello, everyone.
I recently updated to 5.12.11 (from 5.10.41), and now bluetooth seems to be unavailable.

root@delllaptop:~# ls /sys/class/bluetooth/
root@delllaptop:~#It seems as if the support for Bluetooth in Intel Wireless has been dropped.
Has anyone seen the same problem?
